A general rule is to add 1/3 of the dev time on cumulatively for every stop you push it.

eg 400 iso, 20 degrees for 5 mins pushed to 800 would be 6.5 mins, pushed to 1600 approx 8.5 mins, pushed to 3200 approx 11 mins 15 seconds.....thats assuming the dev time is 5 mins if you get me?

Thanks pete. I figured as much but thought there might be issues similar to reciprocity when pushing so much. Will give it a go

I usually have a sink full of water at the right temp (20 degrees) and let the dev tank sit in the sink of water so keep the chemical temps correct when I've got longer dev times.
