A lot of variables here as you know, but I run 33-34 front & 36 PSI Rear, some have said that is too hard as they have a stiffish side wall and makes for an uncomfortable ride, any lower I would be afraid of cupping that I experienced with PR2's.
I probably need to understand the 20% rule better to comment further, maybe Shazam will chime in.
