johnsteinbeck said:one i did find: a quite harsh article on espn "length didn't add up". apparently, by the end of the second set, they were taking 30/33 secs between points, and the writer (reasonably) assumes that the breaks got longer later on. the conclusion of the article (that with swiss timing, so to say, the match would have lasted 50 mins less, because Fed usually takes around 15 secs between points) is a little crude, as of course we have to respect that this was a long and grueling match, and that AO heat is probably gonna slow everyone down.
There's a subtlety here. Let's say that on average they were taking not 33, but 30 seconds. And let's say we are talking ATP and the limit is 25 seconds. One may say that ok, it is just 5 seconds. The problem is that this is on average. There are surely some outliers pulling the average up (the classic example of the case after a long, extenuating point), but there are surely a lot of points were the time between them is quite short, like after an ace/service winner, a double fault, a 3 shots rally, etc. In those cases the time will be probably within the 10-15 seconds range. All that to say something obvious for those familiarized with probability distributions: the standard deviation of this set must be around at least 10 seconds, which means that these guys were taking, roughly in 30, 35% of the time, around 40 seconds between points. This is twice what you can afford in GS play, and in this case, I must agree with the critics: it is a clear rule violation that directly benefits the offender.
On a secondary note, the article's author argument on the line that "if it was Federer serving" is quite silly... it was not, different players, different style, period. If Federer wants to serve in three seconds, good for him...
