gibblet in no way am I stating that you are using two different aiming points. Totally disregard the fact that I figured out the hypotenous of the triangle. I am saying that this is if you use your 20yd pin for both of them.

I know the verticle acceleration will not affect the speed I never stated it would. Both arrows are being affected equally by the verticle acceleration. The fact is the angled arrow has verticle velocity as well as forward velocity.

Zrexpilot, I think we are kind of agreeing because I'm saying that the reason you have less arc on a angled arrow is because of speed, and you are agreeing but you don't really have a reason for less arch.
