Basiclly you have to be good at simple math (such as what is 3/4 of a 200 yard drive and things like that). You also have to master the timing involved with the swing meter; if you don't have the timing the math you just figured out is completely worthless! Finally, you need to get accustomed to how the ball reacts with each player and how the wind affects the ball for each player (since this changes with every character from how high they hit the ball to how wide they hit the ball from left to right or the other way around). After that, there really is nothing else to do but to keep all those things in mind and practice, practce, practice!!!

practice, practice, practice!
