I had to fix the formatting a touch, but I actually posted Paul’s routine that he wrote up in some magazine. Not sure which magazine, but doesn’t really matter I guess.
Basically start ~4" below lockout (quarter squat territory), do 2 sets of 20ish reps. Do that for 3 days. Drop it 3" and drop off 3 reps, so now 7" below lockout, and 2x17ish. Repeat until you’re at 2 sets of 2. Wait a few days, retest maxes, and start over.
