In the 10/20/Life book they talk about doing, for example RPE 7 with one top set. So would I do something like 60%, 65% and then for my last set do 70% (RPE 7)?
As JB mentioned, the RPE indicates a level of effort, not a bar weight. RPE 7 today and RPE 7 after being sick with a cold would be different bar weights, but the same effort level. RPE 7 would mean 3 reps left in the tank, RPE 6 would mean 4. an RPE 10 would be a max. No more reps could have been done.
Your weight choices during your build up sets will have a large effect on the amount of weight you can move for that top set. Making 5lbs jumps and starting a bit heavier would accumulate more fatigue than making 50lbs jumps and starting lighter. It all depends on the day. Ideally, you’ll want to find a point in between my two examples.
