Some Grand Slam Set Data

I recently put together a database of all Open Era GS matches, and was combing through for it for some data that was interesting to me, thought I'd post it here, since I didn't see anything similar.

Nothing is 100% certain, I know there are several errors I caught in the results (from the ITF website), and these were mostly obvious ones, so there are probably some 'hidden' ones, but they should even out.

All data is through the 2009 USO.

Code:
Total matches I count: 19933
5-setters: 3629, 18.2%
4-setters: 5957, 29.9%
3-setters: 9527, 47.8%
2-setters: 758, 3.8%
1-setters: 62, 0.3%
A number of the two and three-setters were from several tournaments in the 70s which were best of threes.

Code:
Most common match patterns:
WWW: 9144
LWWW: 2236
WLWW: 1897
WWLW: 1734
LLWWW: 734
WLLWW: 631
LWLWW: 601
WWLLW: 590
LWWLW: 551
WLWLW: 492
The remainder are three-setters and retirements.

Most common scores:
Code:
6-3 6-4 6-4	167
6-4 6-4 6-4	142
6-3 6-4 6-2	120
6-3 6-2 6-2	113
6-3 6-2 6-4	105
6-4 6-2 6-4	104
6-4 6-4 6-2	103
6-4 6-3 6-3	99
6-3 6-3 6-4	93
6-4 6-2 6-2	91
Most common 4-setters:
Code:
3-6 6-3 6-4 6-4	17
6-4 3-6 6-3 6-4	17
4-6 6-3 6-2 6-2	15
4-6 6-3 6-4 6-2	15
6-4 6-4 3-6 6-3	15
4-6 6-3 6-4 6-4	15
6-3 6-4 3-6 6-3	14
6-7 6-3 6-4 6-4	14
6-4 3-6 6-3 6-2	13
Most common 5-set scores:
Code:
3-6 2-6 6-3 6-3 6-3	5
4-6 4-6 6-3 6-3 6-3	4
6-3 3-6 6-3 3-6 6-4	4
3-6 6-3 3-6 6-3 6-4	4
There's more info I can post, but it's just a matter of me coming up with some more interesting ideas, I'll probably add to this at some point.

Re: Some Grand Slam Set Data

Good job thanks. I had compiled some similar statistics some time ago, but never got past the 00s decade.
As you have already took the job, some questions:

Do the four slams follow the same pattern of distribution?
Did you count retirements (past the 3rd set) as a normal match? (pure curiosity)

I counted retirements as normal matches for the purposes of set length; here are the numbers with them, along with defaults, removed :

Code:
Total matches I count: 19436
5-setters: 3599, 18.5%
4-setters: 5867, 30.2%
3-setters: 9383, 48.3%
2-setters: 587, 3.0%
As for the breakdown of the set differences by event they are here:

One note; I removed from this data all the rounds that were best of three, since they were unevenly distributed, and would tend to skew the results. Also, these results don't have retirements, since I was too lazy to change that when I moved on from your first question.

These rounds, by the ITF data, were:
1970 AO R1
1973 AO R1
1974 AO R1
1982 AO R3-4

1973 RG R1-2
1974 RG R1-2
1975 RG R1-2

1975 USO R1-3
1976 USO R1-3
1977 USO R1-4
1978 USO R1-3

Code:
Tour	3	%	4	%	5	%	Total
AO	1873	48.6%	1237	32.1%	743	19.3%	3853
RG	2406	49.6%	1514	31.2%	926	19.1%	4846
USO	2334	49.8%	1467	31.3%	882	18.8%	4683
W	2534	48.4%	1649	31.5%	1048	20.0%	5231
So, even with the best-of-three matches (which weren't played at an Open Era Wimby), controlled for, Wimbledon still averaged the highest percentage of five-setters. If I threw back in the matches from the rounds listed above, the difference would of course be even greater.

Also, a retirement/default breakdown:
Code:
Tour	
AO	119	3.0%
RG	128	2.6%
USO	152	3.1%
W	91	1.7%
Overall	490	2.6%
This number has sharply increased; 296 of these retirements came in the period 1969-1999, and 201 since.

Another way to look at it; For an average, 127 match GS, across open era history (assuming all matches are best-of-five)
Code:
61 3-setters
39 4-setters
24 5-setters
3 retirements
I'm a little uncertain on the retirement data, since I'm not convinced the ITF results will correctly identify all such matches, but the errors should even out.
