I don't know what you mean by "physical calculations" so I'll wait till you have clarified before answering that.
The thing you should be focusing on is consistency. If you shoot several times from the same location using boulders of different weight, age, and state of disrepair, do you always score the goal, regardless of the battery's state of charge? If you don't have a consistent shooter, it's fruitless to worry to much about polynomial vs piecewise-linear vs lookup table.

by physical calculation i mean calculating the position and height of the ball at a given point with physical equation that include air drag and magnus effect
