2010 WIN/LOSS RATIOS

I've been compiling statistics on the win/loss ratios of players at both the Tour and Challenger level up until last week. Using the arbitrary minimum of fifteen matches (n > 14) for the higher end and seven (n > 6) for the lower end, this results in the rankings of the best and worst performers displayed below*.

It is very interesting to see that five of the players (i.e. Michal Przysiezny, Kei Nishikori, Carsten Ball, Karol Beck, Robin Haase) that score poorly on the ATP level are among the best performers on the Challenger Tour, suggesting that it is really difficult to make the transition.

Agree, great stats!

In fairness Roddick did pretty much skip the clay season which has skewed his win/loss ratio. That said, his performances in the early hard court season means that he merits his place near the top players of the list.

Thanks for these, great work :worship:

Slightly surprised Fed isn't worse (feels like he's been worse), but he's been at 80% in his last 5 tournaments so maybe that explains it. Great from Rafa obviously, and Roddick too.

Clay season puts Nadal at no.1.
Never in doubt.

roddick hasn't had a bad season, he just has underpreformed at the slams and skipped the clay season. think he will be back in the top 10 by the year end

Exactly. Obviously these statistics don't discriminate between surfaces and tiers of tournaments, so a win in tournaments like Newport counts as much as Wimbledon.

Last year, hardly Rafa's best, he played 78 official matches (including 4 DC), losing 14. That's 82% wins. It includes all surfaces but grass, since he skipped that season.

Uhm. How?

Nolby

Uhm. How?

His record was 20-4 heading into Cincy. He went 2-1 in Cincy reaching the Third Round.

Obviously Cincinnati is not yet included, and the results also do not include Davis Cup.

He was 17-5 coming into Cincinnati, with losses to Murray, Djokovic, Nadal, Melzer and Montańes. As I indicated in the first post, retirements and walkovers are counted as losses.

I don't see where you indicated those type of rules in your original post. :shrug:

If those are the rules you are using for these stats, I can tell you just glancing at your list that Nole should be listed with a record of 32-11 instead of 33-11. He has won all 4 of his Davis Cup matches and his record before Cincy was 36-11.

Ah, I am sure I typed it, but must have deleted it when I had some troubles with the [ code ] [ /code ].

Djokovic has 33 wins: http://www.atpworldtour.com/Tennis/Players/Top-Players/Novak-Djokovic.aspx?t=pa.

Logically, if walkovers are counted as a player's loss they are counted as a win for their opponent. I know this is arbitrary, but it is easier when processing.

It's cool. :cool:

Sorry, I'm not trying to be picky. But if Nole has 36 wins before Cincy and 4 of them came via Davis Cup, how does he end up with 33 wins instead of 32?
===============================
EDIT:

Ahhhhh.... Nole has a win by W/O that the ATP site doesn't count to his win total the same way they don't count Nalby's loss by W/O against his record.

Ok, I get you.... :yeah:

I think you can probably see why Nalby fans would rather you use the Win/Loss rules used by the ATP World Tour website. If you had his record at 20-4 (pre-Cincy, counting his 3 DC wins, not counting the match he lost when he withdrew the day before it was played) as the ATP World Tour does, it would give him an 83% winning percentage and make him #2 instead of #4. ;)
