Both Jawge and Mark had answers that are pretty much accepted as fact by most people and their answers were both slightly different. I belong to the group that looks at string follow as Mark does, when the bow is first unbraced after shooting I measure the deformation as opposed to it's rested position when the limbs return to their permanent shape. It is really hard to look at a bows profile and see how it was affected by set, I have seen bows with 2" of set that had strings as tight as a banjo at brace, other bows have one inch of set and sound soft plunky at brace. If your string has a nice crisp feeling at brace height I think you successfully tillered the bow regardless of the set/stringfollow/deflex/ whatever? Steve
