Found out my 1 rep max was around 30kg and decided to do a pyramid set around this. With weights I used to do it in sets of 80%, 70% and 60% of the 1RP but for pull ups I have found that I can't do it. It seems to work if I do the same percentages but taking the percentage of each drop in weight.
Sorry if I’m misunderstanding this, but for working out percentages away from 1 rep max on pull ups, I use bodyweight plus the added weight, so 80% would be around +10kg, assuming you weigh 67 kg.
I just work out the percentages on the weight added. +10kg would be too light for the 3 sets of 3. What I worked out seems to work nicely at the moment and I failed towards the end of the last set so it is probably the right intensity.
I think pullups are odd to get quite right for percentages, and I've wondered if part of the reason is not accounting for the weight of your arms(which are not being moved). I'd guess that arm weight for most fit climbers is probably between 10-15% of body weight.
