Oh, I only meant that most, if not all trainees don't know exactly what their rep maxes are, so it's better to err on the side of caution. Not so much a big 10% deduction lol. If Wendler's benching 600 lbs, running the program at a 10% deduction would certainly ellicit the gains he's after!
Also, I know most trainees aren't current lol. So when you ask them what their 1 RM squatting is, they'll toss out an all time PR from 6 months ago.
