G.O.A.T.
For low level, simple extrapolation is all that's needed.It requires extrapolation that is not at all difficult. If you can't know what your shot is going to do after you hit it then you need to practice the mental faculties you're using there more anyways. When I play real sets I will consistently know I hit a ball long or into the net or perfectly where I wanted to before I see it happen. Sometimes I still surprise myself but the vast majority of times no.
As you get higher, simple extrapolation and assumption won't do anymore. Advanced players need to hit with more precision, eg consistently closer to the line, consistent amount of rpm/topspin. This is why in ATP, rpm is a thing, consistent depth is a thing, precise positioning, placement is a thing.
