There are some topics I think I know as much about as most people, but this isn't one of them, so excuse me gassing on, but i would like to learn something.

What I mean by "the curve" is if we plotted brace height to forgiveness, I don't think the curve would be a straight line. The yikes! factor seems to hit in the 6" range. If one considers the length of the powerstroke, which is the locktime factor from 7-6" on a 20-21" stroke we are only seeing a 5% change which doesn't account for the yikesness of what is happening. On the other hand it is a 16% change in brace height, which is significant, but perhaps still understated. Part of what is going on is that there are multiple factors here. They don't make a C2 with a 5.5" brace height, and how nice would a Gforce be to shoot even with an extra inch of brace height. But nonetheless based on the numbers the culprit seems more in the fact the brace height was lowered than the power stroke was lengthened (did I say the opposite above, well that's what you get with a lot of caffeine). That being the case, it seems to me that it is either the allignment thing, in which case there wouldn't be any problem with a drop away rest (someting I haven't heard said, hey science is difficult). Or maybe it is biomechanical, the brace height, and the arrow leaving the string coincide with something like the wrist joint, and its movement. I'm bailing as fast as I can here...
