Re: Unusual number of 5 sets matches in FO 2012, or am I just imagining it?
OK, got a chance to check my data.
Average number of 5-setters per GS: 23.8.
So there have been 20 so far, but its worth noting that, on average, there are less than 3 per tournament once you get past R3, so there is not much room to grow that number.
This tournament would have to have a scintillating finish to top 2012 AO, which had 24 through R3 and 27 total.
Highest recently is 2010 Wimbledon, with 30, and 2004 USO had 34, which I think is highest of the open era.
So this looks like a average grand slam, a bit more than usual, but recently RG has had fewer than others; the last time it got higher than 22 was 2006, and last year it had just 16.
