Win percentage by age (in progress)

I took the age of the players at the beginning of each tournament (for instance, if you were 21 at the start of the tournament, but turned 22, the entire tournament would just count as 21). I also excluded years where players played fewer than 10 matches.

Asterisks indicate active seasons.

(NOTE: I haven't checked everyone-- just the usual suspects. I'll keep looking, but I thought I'd share first. If you have any suggestions of players who had 1 good year-- particularly at 16/17 or 35+, but might not otherwise have done well, that would be appreciated.)

Re: Win percentage by age (in progress)

Sadly, I just got it from the ATP website (I used Excel to figure out the ages of each player at each tournament, and add everything up.)
