Many posters here have mentioned that the ATP site has a lot of mistakes when it comes to things like titles won, or scorelines. I'm starting this thread as a resource for ATP errors on match statistics.
I'll start with a list of published boxscores that all differ with the ATP stats.
Last week I ran a search in Lexis-Nexis for boxscores from 1991-2000. I just searched for the term "Total Points Won."
I found 7 boxscores. Six had serious discrepancies with the ATP stats on service/return percentages and Total Points Won/Played.
I sent an email to the ATP with a list. I can't say that the boxscores are definitely correct, but I do know that the boxscore I had found for the 1992 W final had accurate figures while the ATP did not.
I also know that the ATP stats for the 1995 AO final are wrong because they clash with my own counts and ESPN's.
On the other hand, while the ATP only agrees with 1 of 7 boxscores I found in that particular search, from time to time I have seen other boxscores that agree with the ATP.
Sometimes I've also seen, not entire boxscores, but individual stats that agreed with the ATP (for example, just the first-serve percentages). Occasionally these stats come from television coverage.
Also, when we've done our own counts, I can't recall a time when our numbers differed from the ATP stats by a lot. In fact we've done a few matches where our own counts for the total number of points agree with the ATP. We've also come up with slight discrepancies, but with the boxscores we're talking about large differences on things like total points played in the match.
Later I’ll make some posts on ATP stats that are look okay.
For now let me just list all the boxscores I know about that clash with the ATP stats on service/return percentages and Total Points Won/Played.
A list of the matches:
Agassi-Ivanisevic, 1992 Wimbledon final
Bruguera-Courier, 1993 French Open final
Courier-Edberg, 1993 Wimbledon semifinal
Sampras-Agassi, 1995 U.S. Open final
Krajicek-Washington, 1996 Wimbledon final
Sampras-Moya, 1997 Australian Open final
Korda-Sampras, 1997 U.S. Open
Korda-Rios, 1998 Australian Open final
Rafter-Philippoussis, 1998 U.S. Open final
And here are the actual boxscores. I've been able just to cut and paste them in here; the boxes are gone but the numbers look readable.

In every one of these cases, the ATP's aces, doubles, break points and number of service games look okay, or at least they resemble the boxscore figures. The remaining ATP stats are sometimes off by so much that they don't appear to belong to the match in question.
Some other discrepancies I've seen:
- For Agassi-Sampras, 1995 Australian Open, my own counts contradict the ATP stats on points won/played on service and overall.
- For Sampras-Hrbaty, 1997 Australian Open, 4th round (6-7 (7-4) 6-3 6-4 3-6 6-4), The Australian reported that Sampras led Hrbaty in total points by 157-154 (the ATP has 189-184); that Hrbaty led in aces by 20-17 (the ATP has 21-17); and that Hrbaty converted 3 of 10 break points (in agreement with the ATP).
Maybe if we get enough people e-mailing the ATP we'll get a response.
