I actually posted this in a topic on another forum, but would love to see it discussed here:
"Brace height adjustment (assuming you aren't way off with it), in reality is simply a fine tuning practice to an already fairly closely tuned setup.
Once the brace height of a bow is set within the optimum window of the bow's preload, changing of the brace height within that window of setting has no significant effect on performance, therefore has no significant effect on the spine requirement of the arrow due to performance shift.
Going outside that brace height window of optimal preload (either up, or down) will decrease the performance of the bow, so if changing the brace height does have some significant enhancement to performance, it is highly likely you were way off with the brace height to begin with.
The only power stroke length, that has any significant effect on bow performance, and arrow spine requirement is draw length, and obviously the longer the better.
What changing brace height "does do", is change the angle of the arrow in relation to the strike plate, which in effect has the same outcome as changing the center shot of the bow.
The lower the brace height, the lower the spine requirement of the arrow will be, which is similar to moving the arrow more outside of center. SO, if your arrows are shooting a bit weak, lower the brace height. If a lot weak, then you need to revisit your arrow build.
The higher the brace height, the higher the spine requirement of the arrow will be, which is similar to bringing the arrow closer to center shot. SO, if your arrows are shooting a bit stiff, raise the brace height. If a lot stiff, then you need to revisit your arrow build."
Throw in your 2 cents.
