you can find out percentage of first and second serves. and what do you say to critics that might say, well, they want to keep tennis a bit more traditional, this is almost cheating? not happening. i think it will hurt our sport if we went that way. everyone talks about mistakes all the time, but you first want to know what your strength is. so there is a combination of things you can learn with the microsoft tablet. you want to look at, 0k, what do i do really well? like your dad was getting the serve down the middle really well. but that verifies it so that you go, ok, i'm on the right track. but you've got to know your strengths in life — it really relates to life as well. but when you look there and you see these stats — i wish — oh, my god — i would have given anything to have what you guys have because i like all this, i love information, i love learning, i love all these things, and our generation, we couldn't even look at videos. and she's not the only one thinking that using this kind of tech can be beneficial.
