I think the general agreement by most is that the math is VERY complex if you include all the contributing factors, but in reality it's not that important in the long run. I think teams should definitely put thought into the trajectory of their throwers, but anything beyond simple kinematic equations is going to be wasted effort. I think the quote from Ian Curtis put it best,

Entire books have been written on drag, but FIRST robots tend to operate pretty well on the back of a napkin.

Rather than worry about every little detail that could potentially throw off a throw, people need to realize that this game, by it's nature, is going to be full of variables. Heck, the balls are going to get sliced up, no doubt, so that right there is going to throw off any calculations of drag. The best thing to do is to do basic calculations to get a good idea, then build a shooter that is consistent, and try to get as accurate as you can but accept the fact that there will always be percent error. The old expression goes "measure with a micrometer, mark with chalk, cut with an ax."
