Len: Believe me I have studied how arrows leave the bow and I am amazed that they clear the bow as well as they do. The Beiter site has slo-mo pictures that show just how much flexing is going on upon release of the arrow. What I have found that works well with the biscuit is to start the tuning with the bow at an even tiller, the biscuit parallel to the bowstring and the arrow nocked at 90degrees to the bowstring. Every bow is its own collection of stresses and biases but most right-handed bows that I've worked with seemed to be pitching the arrow about 1/8" to the left of the centerline of the bow and that has been consistently where the rest usually has to be for the bow to shoot its narrowest groups. If you actually read my last dozen posts you probably already know that I adjust the tiller to get a level arrow in the target and leave the nockpoint at 90degrees. None of what I do requires a bowsquare or a lazer its just oldfashion shoot the bow logic that gets the job done. I've got a drawer full of old rests and a handful of my own handbuilt rests and none of them are as good as the whisker biscuit. I can admit when my own work has been surpassed and the biscuit has got me beat. The biscuit is a very consistent rest. My current bow is a Newberry B-1 and its shooting 273FPS through the biscuit and grouping Magnus broadheads inside of an inch at 25yards. Fieldpoints clack together so often that it makes me nervous and I end up spending as much time inspecting the shafts as I do shooting them. The biscuit is a different rest to tune, whatever it does to arrowflight it does from 360degrees around the arrow. There is no springboard and no temporary now its here and now it isn't thing going on with the biscuit. I like the biscuit because I can understand how it works. Fix the bow so it pitches the arrow straight through the middle of the biscuit and the arrows fly like darts and there is no fletching wear worthy of mention. Fortunately none of this is brain surgery, but it is just common sense. Good luck hunting!
