Mentor types, with this advocacy of decreased tension or less than taut canvas and leather, you guys may encourage me to become a sloppy stropper - heaven forfend.

To help heaven in this defense, if I put my strop in front of a mirror or put a mirror behind my strop, how much deflection should I be aiming for? A half inch? Five eights of an inch? Thirteen thirty twos? A hint, a clue would be so greatly appreciated.
