Along the way, we dig into who wins long rallies, who loses long rallies with UFEs, who makes the most of their late-rally shots, why we need winner rates to estimate shot tolerance, and that's not even all of it...

@Wesleyw152 Not that I know of. Some grand slam sites have published leaderboards for specific tournaments.

In the full post, I dive into why speed doesn't tell the whole story of his second serves, then look for players who have made positive moves from sub-50% second-serve win rates:

@sarmatron I don't. Closest I have is consolidation% -- how often a player holds after breaking -- and that for only a subset of matches. E.g. I'm skeptical there's much there, beyond "better players are better at this," but I'm tempted to look into it.

@Lord_Kartz every detail, no. But it must be close to correct or the spreadsheet will think you're entering different point winners/losers, or my parser throws errors. Even if people get things backwards, it's shows up in the data--like a suspiciously high number of inside-in forehands.
