Mike,

This might be a stupid question, but I can't seem to find the answer in the book. What should I do if say I overshoot my target RPE of the day? For example, if I was supposed to hit triples @8-9 with 5% fatigue percent, but I made a weight jump too high and I hit a triple @ 10. Does that make it a 4% fatigue percent, since I went up from 9 to 10 RPE and move on to the next exercise. Or should I just accept it and drop back to the 5% fatigue percent?

 Thanks 

Unless you did the same weight and reps twice (once @9 then @10) there isn't any information to base your fatigue off yet. You either over estimated your ability or were having a bad day.

I normally just use the percentage chart or just go by feel as to what weight would have been @9 and take the fatigue percentage from that.

Thanks!

 I gotta get down to customise my RPE chart one of these days
