is there a statistic?

[reformed]

what percent of players that win the 2nd set to force a 3rd in a 3 set match actually win the match?

rough estimates are welcome

Not sure about a site with percentages posted but I've got a spreadsheet where you can work it out in 5 minutes or so.

That's the page itself, it updates 2011 results pretty quickly, very useful site.

Seemed interesting so I looked myself, in 2010 ATP matches were 352-344 for players winning the 2nd and 3rd (50.6%)

WTA was 392-346 (53.1%)
