PCC

Is the calculation available anywhere?

I don't know calculation..but from a logical/ mathematical perspective..if the system is based on a trimed average performance..when you start to bringing values into an average that were abnormal and with excessive correction..it will impact on your average.

8 scores are discarded..so you kind of have to accept that these days have no legitimatacy in working out an accurate average .

If we ignored Golf for a second..if you have 20 values..and your trying to predict what will happen next ...if this is influenced by bad data or corrected data. You will have difficulties. The system does not want outlier days ..

Now to counter that ..the problem WHS is ..it doesn't sufficiently correct for local conditions and we play golf in what you described a fair bit...

But the argument will be made ..8 scores have to drop anyway ..just let that one go ..some are going to go..so let the the tough days go..

Sorry ..your question is exact PCC calculation..I don't know ...very odd you can't find it ..

They have said in a few places that they had to keep it secret

I think they leaked at one point that is similar the old calculation (based on categories). But they also admitted they changed the parameters this year so that it would be 0 less often

The best way I can explain it.

36 points is not normal standard scratch anymore. 34 points is actually closer to standard scratch and you can see that from your 8 counting rounds for your handicap. Typically you will have a couple of scores higher than 36 points and the rest roughly 36/35/34 points each or there or thereabouts. A score of 35 points or better will reduce your handicap most of the time (the time it doesnt is when you're knocking out a good score).

The PCC works the same way. It treats 34 as standard scratch. It looks at single handicap golfers and judges how they played the course to determine PCC as typically single handicap golfers would be more consistent than higher handicap golfers. If all the single handicap golfers played rubbish, it gives a PCC score of 2 or 3. If 10% of them played it to 34 points, it will give a PCC of 1 and then if more than 10% played to 34 or better it gives a PCC of zero.

I think I saw the leaked table before and it looked something like this ::

10% of single figure golfers beat 36 points - NO PCC

10% of single figure golfers in range 34-36 - PCC 1 (other 90% worse than 34)

10% single figure golfers in range 32-34 - PCC 2 (other 90% worse than 32)

10% single figure golfers in range 30-32 - PCC 3 (other 90% worse than 30)

Now that might not be exact, but the leaked table I saw looked something like that. And thats why you see very few PCC calculations. You probably mostly see them on days where next to no single handicap golfers played.

1/2 a shot. like 0.5 ? That would be fairly correct.

Played in a comp a couple of weeks back in horrendous conditions, strong wind and sheets of rain. The results showed two people in the field out of 42 entries played to their handicap. PCC was 0.

I read last year (I think) that the algorithm was wrong and not calculating the PCC correctly. It was changed and I noticed PCCs of 1 and 2 started getting applied when things were tough, as you'd expect. I don't think there has been a PCC above 0 at our club since May though, there have definitely been days that would have warranted it.

I think WHS is a good system. It's a different system, and I think people need to stop thinking that it is supposed to replicate the old system when it's not. It's a more accurate reflection of how you're playing at that point in time - your handicap can come down very quickly but also go up just as quick if scores start dropping out and you're not replacing them. It also makes me less likely to give up on a bad round as it could end up being my 8th best score in the future, so I'll want to limit how much my handicap can increase.

It was a reply to a previous comment about the system.

Who says it's not working correctly?

Come back with the numbers and then you can actually try to understand if it's working or not - ie scores and handicaps. I just looked, I've had PCC applied in 6 of my 22 rounds this year - and that's starting in May. Clearly there are reasons it's not being applied on the days people think they should, the scores aren't as bad as you think they are.

In my last 20 scores, which goes back to September 2022 (I really don't get enough qualifying golf in) I have 2 rounds with a PCC, one in a near hurricane down in Rosslare where 1 woman broke 36 points on the day. Easily a 3 club wind.

The other in Greystones at an open when the conditions were fine for playing but scoring must have been low with a lot of away players out?

last Friday out of 31 in tier 1. 3 equalled or bettered 36 pts . no pcc

I had another PCC yesterday, not at my home course either.

To be fair it doesn't seem to be getting applied either direction in my place at all.

Under the old system we would often get a CSS of 37 points if we got warm dry weather in the summer but I haven't seen anything other than 0 at my home place in general

Were there many low handicap players playing? I have a feeling it's weighted to their scores

could you post what pts they got ..

Again - we just don't seem to want to accept that a wild day during and after a storm is not best to be applying an adjustment / forcing that round into your WHS - the PCC is very conservative - as we have 12 rounds that will be discarded in your 20.

Irish golfers will just have to accept that WHS is giving you an average and tries to not adjust rounds - as it does not want to be an adjusted average - as you are already removing all the outlier days in the 12.

I think it is a carry over of people thinking we are in old system.

I accept the system is very conservative - particularly for Irish conditions - but there is no way you have 12 days out of 20 that are abnormal. So the 8 rounds are the key to focus on.

From Rikand. - but was from his memory

10% of single figure golfers beat 36 points - NO PCC

10% of single figure golfers in range 34-36 - PCC 1 (other 90% worse than 34)

Careful Bobster. Your already 3 shots down for killarney .👹
