    actually

    im pretty sure i was able to export from club end when i was mucking around with it a while back… maybe ask your handicap sec if he can export information for yo



  • Registered Users, Registered Users 2 Posts: 424 ✭✭REFLINE1


    yes that might be the way to go but knowing them id be quicker to manually type the scores in myself 😂



  • Registered Users, Registered Users 2 Posts: 1,749 ✭✭✭coillcam


    Short answer for GI is no and Masterscoreboard I'm not familiar with. I was looking for the same thing with GI/Clubv1 to help my club's handicap lads but to no avail. Maybe in future they'll make it easier. For now I think you need to manually do it or try to dump the page to excel/pdf in some way and manipulate it. Some smart person probably knows how to use python/data scraping tools to extract it but that is well beyond my means.



  • Registered Users, Registered Users 2 Posts: 424 ✭✭REFLINE1


    Thanks. I just bit the bullet and spent a few hours last night plugging them into excel. I've a spreadsheet going where its working out my course/hole index based on my average scores at home course. An interesting exercise. My Index 1 based on my scores is the course index 2 but my index 2,3 & 4 are course index 7,13 &15. There's some obvious low hanging fruit in terms of my strategy on those holes for instance. I've excluded extreme outliers and result is pretty much the same holes I'm clocking up big scores on.



  • Registered Users, Registered Users 2 Posts: 807 ✭✭✭bobster453


    Does Howdidido not include this or similar in Stats section?



  • Registered Users Posts: 239 ✭✭Fotish


    I see the 12 hole and 14 hole competitions are now counting for Handicap purposes.

    Do the 12 hole competitions have to start on the first hole or can the competition start some other place on the course , say the 4th hole ?



  • Registered Users Posts: 239 ✭✭Fotish

    Ask your Handicap Secretary to email you a copy of your Handicap Certificate, you are entitled to that.

    It will be in PDF format and can be downloaded and edited .



  • Registered Users, Registered Users 2 Posts: 1,749 ✭✭✭coillcam


    You need to complete a full 9 hole (rated) course minimum and then the system finishes the rest.

    So if you play 1-10 holes it will calculate for 11-18 using an algorithm. The same if you play 1-15, 16-18 get calculated.

    The algorithm is based on the expected score for your handicap on a course of "standard difficulty".

    Note that if holes are turned off it doesn't work. Eg hole 4 on the front is closed and you play 1-3, 5-13. You can't get a WHS counting score as you haven't played a full 9-hole rate course (eg 1-9 or 10-18).



  • Registered Users, Registered Users 2 Posts: 21,377 ✭✭✭✭PARlance


    Just to add to that, once a full 9 is played, the other 9 can be sliced and diced. Our 10 hole (1-10) moved to a 13 hole this week (1-11,15, and 18).

    The move to qualifying has been a huge success in our club imo. Average winning scores are down about 5 shots and lets just say that the winners enclosure has a new lease of life.

    We had a 21 win the 10 hole one week. 31 wasn't unusual last year.

    Thank you for that, it sounds entirely sensible.

    I couldn’t find anything about it on GolfIreland, do you know of anyplace it is documented so I can reference it to people making enquiries to me, thanks .

    When you say scores have been reduced this year, is that because players Handicap Indices have been reduced ( because of the new 12 hole 14 hole course rules ? )



  • Registered Users, Registered Users 2 Posts: 1,749 ✭✭✭coillcam


    That was parlance who mentioned scores being reduced in a 10 hole comp vs the same non counting comp last year.

    In a non counting comp, players tend to have higher scores. Mostly as the pressure is off and they know it doesn't affect their handicap. They are also usually using forward tees which might not be rated and have placing/cleaning everywhere. This makes it much easier to score.

    There is also a small cohort who "protect" their handicap in counting comps. When they realise a good score is likely they pull the handbrake with a few holes left to have a score that is not good enough to appear on their record. Not happy that their score will win a big comp or 1st place so they are just bandits and everyone despises it.

    When a comp is counting it's "real" golf on proper tees with no placing.

    Typically most non-counting golf is during winter time anyway. Being able to have 10-17 holes counting is brilliant.

    I don't buy that at all. a comp is a comp.



  • Registered Users, Registered Users 2 Posts: 807 ✭✭✭bobster453


    True for ya.I try my damnedest every comp.Fact i am useless doesnt srop me trying😁



  • Registered Users, Registered Users 2 Posts: 424 ✭✭REFLINE1


    my club use masterscoreboard and it doesn't have much functionality for this as far as i can see. does some stats for your last 5 rounds only.



  • Registered Users, Registered Users 2 Posts: 1,834 ✭✭✭Golfgraffix


    not true, Handicapmaster gives stats for every hole along with your best and worst on each hole

  • Registered Users, Registered Users 2 Posts: 1,834 ✭✭✭Golfgraffix


    just look under the mygolf section.



  • Registered Users, Registered Users 2 Posts: 1,186 ✭✭✭OEP


    Definitely not. I don't care when it's not counting



  • Registered Users, Registered Users 2 Posts: 424 ✭✭REFLINE1


    yes but it only shows "Displaying records covering last 1 month (or last 5 competitions processed)." I don't see an option for any analysis for a bigger sample than that?



  • Registered Users, Registered Users 2 Posts: 1,040 ✭✭✭paulos53


    That must be something set by your club. Mine says "Displaying records covering last 9 months (or last 15 competitions processed)."



  • Registered Users, Registered Users 2 Posts: 424 ✭✭REFLINE1


    yeh that makes sense because there doesn't seem to be anyway of changing the setting at my end.

    Is there any adjustment in WHS for weather conditions? Had 34pts on Saturday in a mini hurricane - definitely 3/4 shots harder than it would normally be and I actually went up in handicap. I know I must have knocked out a better score but it seems pointless to play in bad weather now if this is the case.



  • Registered Users, Registered Users 2 Posts: 1,834 ✭✭✭Golfgraffix


    that is decided by your club, you can go back as far as 24 months in the setup settings



  • Registered Users, Registered Users 2 Posts: 8,651 ✭✭✭spacecoyote


    There is a thing called PCC now, which is similar to the old CSS, it can adjust the difficulty from -1 to +3 shots (so 1 shot easier to 3 shots harder).

    It's not driven by weather but by scoring, and it's tricky to find the actual calculation anywhere. I know they changed the calc in the last year or so to make them be applied more often

    It should be clear on the app if you look at the round to see if there is a PCC applied. In essence, a PCC of 2 would turn your 34 point round into the equivalent of a 36 point round.



  • Registered Users Posts: 275 ✭✭Quahog217


    Perfect thank you, is done automatically or by your club?



  • Administrators Posts: 54,168 Admin ✭✭✭✭✭awec


    It's done automatically.

    It's quite conservative too, I think scores need to be really obviously abnormal for it to apply a PCC other than 0. I have 29 scores on my record for this year and 27 of them have a PCC of 0.



  • Registered Users Posts: 275 ✭✭Quahog217




  • Registered Users, Registered Users 2 Posts: 202 ✭✭Sorbet


    Really interesting thanks. Had a look at Corballis with BGS this year as that’s the hardest conditions I recall playing in and sure enough a PCC of 3.



  • Registered Users, Registered Users 2 Posts: 638 ✭✭✭bakerbhoy


    I think there needs to be a

    Min % of cat 1/2 players to have played before it can be applied.

    At least that was the case.



  • Registered Users Posts: 128 ✭✭zocklie


    I played a SC this year and had a PCC of -1, thought I had played well…



  • Administrators Posts: 54,168 Admin ✭✭✭✭✭awec


    Does anyone know exactly how PCC is applied to a score? Is it literally just taken off / added onto the differential?

    I played yesterday and the PCC is showing as -1. Am I right in saying that this means the scores were higher than usual?

    I shot 11 over through 9 (was a 9 hole comp). This ended up giving me an overall score differential of 25.5. I'm a bit confused as to how it arrives at the this differential from a 9 hole score. Can anyone help me understand?



  • Advertisement
  • Registered Users, Registered Users 2 Posts: 8,651 ✭✭✭spacecoyote


    This is the standard 18 hole calc:

    (113 / Slope Rating) x (Adjusted Gross Score - Course Rating - PCC adjustment)

    And I've attached a doc here that shows the 9-hole score details



  • Registered Users, Registered Users 2 Posts: 1,749 ✭✭✭coillcam


    Forgetting PCC for a moment, the system will take any 9-17 hole and mark it up to 18. Your score for the holes completed + calculated score for your handicap on a course of standard difficulty using the remaing holes.

    Say your +11 through 9 was a real "+12" differential relative to the course/slope. An additional 13.5 is applied for the remaining 9 holes based on your handicap. Note there is no visibility of this calculation from GI/WHS.

    If you had a "+5" differential on the front 9 at the same handicap, the remaining 13.5 would still apply for the missing holes and again you'd have no visibility just a final overall differential.

    PCC in theory should be clear as it is supposedly determined based on standard deviation in expected scoring on a given day for the specific course/tees. However, I think it's a bit murky. We had a medal comp last week and more than 30% of the field shot par or better. Net -3 wouldn't make the top ten. It's a big outlier in our medal comps and the course played very easy that day. Fully expected a PCC adjustment but nothing happened



  • Administrators Posts: 54,168 Admin ✭✭✭✭✭awec




  • Administrators Posts: 54,168 Admin ✭✭✭✭✭awec


    Yea, so am I right in thinking that by and large playing 9 hole comps will see your handicap move slower as at least half of your score differential is going to be based on an average for your handicap, and not at all related to how you actually played the 9 holes you did play.

    The Golf Ireland app really should show exactly how a given differential was calculated.

    Also confused about PCC because I don't think the scores last night were unusual compared to weeks with PCC of 0.



  • Registered Users, Registered Users 2 Posts: 1,749 ✭✭✭coillcam


    Not necessarily but the differential will vary by how hard or difficult the course was and the number of holes played. You can play 9-17 holes to your hearts' content. However, if you go to play competitions/opens then you might not be eligible to win prizes. Many clubs will say you must have a minimum number of counting (18 hole) comps on your record and fully developed index. The goal of the WHS here is to try to get more people to have handicaps and also to have more scores on people's record. In theory the more scores on your record, the more accurate and up-to-date it should be relative to how you're playing.

    I don't think GI will ever show this differential calculation or the logic behind it. You can figure it out by calculating the 9 hole differential as the 9 hole courses will have a slope/rating and then subtracting the difference to the overall differential. Unfortunately for 10-17 hole cards you don't have a slope/rating for those holes so you can't subtract it.

    The PCC calculation is shrouded in mystery because it's considered proprietary and won't be published. You could have half the field shooting the lights out and the last 20% being miles off their handicap range. It's supposed to all balance out but in the absence of any transparency, it's hard to know. All I can say is I have never seen so many net 68 or better returns in a medal but no PCC on the day.



  • Registered Users, Registered Users 2 Posts: 195 ✭✭Brusna


    For anyone interested the score differential calculation for a 9 hole round is:

    (113/Slope)(AGS-CR)+(HI x .52 + 1.2)




  • Registered Users, Registered Users 2 Posts: 2,007 ✭✭✭almostover


    Having been in favour of the WHS when first introduced I'm now really sick of it. My home course is not long, or heavily bunkered but it's tight off the tee and has small undulating greens. Most of which are raised, so when you miss the ball goes quite a bit away. I'm an 8.4 index and only get 7 shots, best round I've had this year is 37pts, find it very hard to score well at home. Had 39pts on my first open singles at another club that is 300-400 yd longer but more open and larger greens. I had 10 shots there. No way it's 3 shots harder than my home course. Didn't play unreal but it was more forgiving.

    Then our captains prize this weekend. I qualified with a nett 70 and played decent. Leading qualifier was a 35hcp who's playing golf with years and had a nett 60. Ridiculous. Next best qualifiers had a nett 65. I would have had to shoot a -6 gross in the 9 hole playoff just to catch him if he played to his handicap, which was 18 shots for 9 holes. It's a joke.



  • Registered Users, Registered Users 2 Posts: 807 ✭✭✭bobster453


    I often think an 18 handicapper off old system would need to be 25 or 26 now just to stand still.



  • Registered Users, Registered Users 2 Posts: 2,608 ✭✭✭newport2


    My wife played in a foursomes competition she and a friend qualified for last week. The played off half of their combined handicaps, which was 18. The eventual winners were playing off 56.

    I generally think the WHS is much fairer than the old congu system.

    I think it is good that 9 hole competitions now count, but I think the changes they give are too severe in either direction. I.e. if the system calculates a cut of 0.4, I think this should only be 0.2 if you played 9 holes.



  • Registered Users, Registered Users 2 Posts: 16,084 ✭✭✭✭Seve OB


    but 9 hole competition always counted towards handicap so no real difference there.

    The system doesn’t calculate cuts. It calculates score differentials. Playing a really good round doesn’t necessarily mean a cut will be applied to a Handicap Index.

    The system works out a score differential that keeps the SD for the 9 holes actually played consistent, so to half it would be disingenuous



  • Registered Users, Registered Users 2 Posts: 638 ✭✭✭bakerbhoy


    WHS uses averages … that why is fuuuucked up..

    Anyone heard of median…

    Mush better metric…



  • Registered Users, Registered Users 2 Posts: 5,927 ✭✭✭Russman


    "Playing a really good round doesn’t necessarily mean a cut will be applied to a Handicap Index."

    That's exactly the part that I've had so many conversations about, particularly with older guys that I play with, my own father included. A lot of them simply cannot change their thinking away from "good round = automatic cut". I don't actually blame them tbh, after whatever number of years of CONGU, its hard to think of handicaps as something new, and to be fair the idea that two guys could shoot 35pts and one could get cut and one could get an increase is pretty off the wall for some people.

    I had a situation about a month ago where an average enough score on the Saturday of 35pts got me a reduction because the worst of my counting 8 was dropping out, and coincidentally on the Sunday a better score of 36pts got me an increase because the best of my counting 8 was also dropping out. I know its done by gross scores and all that, but trying to explain it to the regular 4 ball was funny !! Actually it might have been Sunday to Saturday, but it was consecutive rounds.

    Meh, I know its here to stay, but I have to admit to coming full 180 on WHS, thinking it was great at the start, but now I think its absolutely awful in an Irish golfing context.



  • Registered Users Posts: 4,605 ✭✭✭blue note


    The course ratings being off was my main concern with WHS before it came into effect and it's proving to be a huge issue with it as far as I can see. I've no idea why they don't look at the scores and tweak the ratings based on that. At this stage we literally have millions of rounds to look at data on. Every course must have 10s of thousands. The score differential across different courses should be consistent.

    For example - lets say a golfer with a handicap index of 18 on an away course (based on those millions of rounds) is expected to have an average score differential of 21. If on one course the handicap index 18 golfer over the last few years have averaged 19 and on anther they've averaged 23, then clearly the ratings are wrong. Because that same golfer on those two different courses would have a significantly different handicap. You could similarly look at away scores for golfers. If a clubs golfers away scores are better or worse than expected, there must be a problem with the ratings. Now you can try to confuse the issue by saying there's more to the calc than just looking at the average and there of course is. But the underlying truth is that you should be able to predict scores in that volume with reasonable accuracy. If clubs are out of line with expectation, they should at a minimum be looked at and more than likely adjusted.



  • Registered Users Posts: 696 ✭✭✭fungie


    Why is median better in this instance? Mean would take into account the actual score differential where median wouldn't.

  • Registered Users, Registered Users 2 Posts: 8,651 ✭✭✭spacecoyote


    The critical issues, ultimately, are that, 1, new golfers in most clubs are being left to the system to generate your handicap, and 2, the soft/hard caps are too high.

    Whereas before, when you joined a club, you gave in 3 cards and were given an initial handicap, and it was likely somewhere in the range of 16-20 or so. It was probably tough for a new golfer, but made you work at it. Now I think most handicap secs are just letting the handicap system do its thing. So a guy who would have been given 18 starting out, now is playing off 30 for his first handicap.

    Then allowing people to move from up 1 shot in a year to 5 means handicaps have stretched too quickly, and it's open to abuse.



  • Administrators Posts: 54,168 Admin ✭✭✭✭✭awec


    Maybe average of the your best 8 out of 20 is too wide a spread?

    Average of your best 5 out of the last 20 would drag handicaps down a bit, more so for higher players who are likely to have a much wider variance between their best and their 8th best.



  • Registered Users, Registered Users 2 Posts: 638 ✭✭✭bakerbhoy


    The median is 

    less affected by outliers and skewed data

     than the mean and is usually the preferred measure of central tendency when the distribution is not symmetrical.



  • Registered Users, Registered Users 2 Posts: 5,927 ✭✭✭Russman


    I think there's a lot of truth in that. The question i'm slightly conflicted over (insofar as any of this actually matters 😁!), is that the nature of WHS makes huge volatility almost necessary or an integral part of it. Introducing lower caps makes it a kind of hybrid with CONGU. Almost like "….yeah, its your average but not too much….." The whole premise of WHS is to be a measure of current form rather than CONGU which was always regarded as potential. I'm not sure they are compatible tbh.

    I know ultimately the answer is we have to change our mindset, but its easier said than done !



  • Registered Users, Registered Users 2 Posts: 16,084 ✭✭✭✭Seve OB


    I always felt there were considerable flaws with WHS. main ones being what’s just been said here, hard and soft caps to big, a tighter average would be better and no account taken of proven potential.

    I have long come to the conclusion though that it is what it is and there is not a lot any of us can do about it unfortunately. I do think the powers that be need to listen to the players, maybe conduct some sort of survey for feedback. but they never did and just did their own thing when coming up with the system which was supposed to be the best bits of all the different handicap jurisdictions but in reality was just a small tweak to the USGA version.

    I just accept it now for what it is.
