^^ Actually it is similar in vein to the eternal 5x5 scheme. The idea is to use a weight repeatedly so that your total work sets are comprised of essentially a max. Weightlifters use this for gaining strength and hypertrophy in a 10 sets of 3 reps scheme. It allows a great volume at high % of max.
Working up to a peak is cummulative fatigue (unless done slightly differently from the norm, such that you warm-up and then hit a max before running down to a drop set), and I'm not a big fan.
