Actually only shot distance affects targeting variation (or recoil range). Its just 2D trigonometry (launch angle on x/z is all that matters for accuracy and y angle and force determine the distance)Haven't really studied the science of it all but with a higher arcing shot it seems the ball travels further on its path to the rim... and would lead to some additional variance... making it a harder shot. There will be a few shots that rim out when you are outside of the ideal arc... either too flat or too much arc... but it won't be a huge difference.
If it works it works... I just need to see it more to believe.
