That has to be the most ridiculous analysis of something you have clearly never done, ever. But you have much more time and inclination to run with this nonsense than me so have at it.
Why don't you go to the tennis and try shoot?
Lets assume that you're a pleb, up in the stands somewhere...
On serve you are shooting the receiver and you're focused on the receiver...
It takes maybe 60ms for the sound of the racquet hitting the ball on serve to reach you, then shutter lag of 36ms plus auditory response time of 150ms. The ball will be at the receiver within 600ms of it hitting the racquet so if you want to shoot the ball arriving at the receiver, you can delay by no more than 350ms or just start shooting when you hear racquet on ball. Getting the ball with receiver in shot without shotgun shooting is very difficult.
Assume for pros that are sitting courtside that they've just got brain response plus shutter lag to deal with, so if they respond to the racquet sound then they have an extra 40ms.
What about shooting based on what you see? Light travels faster than sound, right? Moving your head will take too long. Plus it takes longer for the brain to respond to visual stimuli. (http://www.ceejpublishing.com/Articles/0023.htm)
Call this analysis of shooting at tennis ridiculous all you like but I have seen pros shoot this way. Filling CF cards or a laptop hard drive with shots you throw away costs $0. Missing the magic moment can cost $$$.
Or the numbers on baseball...
9 innings, 2 teams, average of 15 pitches per innings... 270 pitches per game on a day. If you only shoot the batter, maybe 2700 shots per day (you start shooting when he starts to move in response to the pitch.) Now I can see why people think baseball is boring - not very much action
