I get 92% on HCs, 91% on "all surfaces", which is not really helpful since that is from very little on clay. Better to look at 84% on clay and see where that goes to.
Well, of course it will decline if you are looking at an average on all surfaces. Then it will go up in the grass season. Then it will settle somewhere after W. That's why it is not so good to look at averages on all surfaces. But Fed is at 84% of service games for a career, so I actually anticipate that his serving stats will go up on clay.
...His
overall career service statistics on clay will probably improve with this season (as they have been ever since his first few seasons on tour, which drag down his net totals), but I suspect he will hold substantially less than 91% through the clay court season, meaning that his season-to-date services games won percentage will be less. He has a career average of 89% service games won on hard courts compared with 84% on clay; his 91% overall-service-games-won average through 2015 Monte Carlo consists in 19 hard court matches and one clay court match, which is a figure disproportionately slanted toward the one of the two main tour surfaces on which Federer holds serve more often. As I said, Veroniquem has not made a sound comparison. Consider:
If a player who, on average, holds 90% of his service games on non-clay courts and 85% on clay plays 20 matches, one of them on clay (as Federer did through Monte Carlo 2015), he will be projected to hold 89.75% of his total service games. On the other hand, if he plays 20 matches,
six of them on clay (more proportionally representative of an actual ATP tennis season), the projection slips to 88.5% of his total service games won.
Exactly. Because we can't compare this part of the season to stats for other seasons, same time frame. Those stats are not available, at least to us.
Well, we
can, because we do have access to his statistics from each match, but we would have to go through his record and add up the respective totals one match at a time, which would take a while. I will admit that I find this spurious "Federer's-statistics-are-the-best-of-his-career" argument irksome enough that I'm tempted to set aside the time to do it.
That's a very good point. By the way, do you know if mini-breaks are counted along with BPs of regular games?
That would change things.
Let's say you have to players in a Isner like score where you have 7/6, 6/7, 7/6, and both players are not broken.
Both players will save 100% of break points against them and will have 0% of possible conversions of BP. That's a wash.
But if min-breaks are counted the winner will have 2, the other guy will have 1. Those SHOULD be counted somehow, but I don't know if they are.
Mini-breaks do not count as breaks/break points; that would warp statistics tremendously. Breaks and break points come only in service games. You can verify this by noting that matches like the hypothetical three-tiebreak match you've mentioned list no breaks or break points for either player in their statistical breakdowns.
I don't think Fed will stay long at winning only 25% of TBs though.
Yes, I'm sure his tiebreak average will improve as the season progresses (and it stands at 20%, not 25%). However, the point nevertheless stands that his tiebreak record thus far this year is a real and significant contrast to what he delivered at his peak; where a 1% difference in average service or return games won through a limited sample of matches is a fairly negligible difference which is not particularly likely to swing the outcomes of matches, a dominant winning record in tiebreaks compared with an abysmal losing one is an actual significant performance gulf, as tiebreaks are much more important than individual service or return games and the gap in performance (which may not even
exist in the case of the service/return games, pending statistics on Federer's performance through Monte Carlo in past seasons) is much larger.
