Re: Alternative player ranking system

I may also announce that the work on a rolling 52 week Elo ranking is progressing really well. I might be able to start posting this ranking experimentally as of next week. I had to make a transition of my database from sqlite to mysql to enable this development, because the amount of data started to overwhelm capabilities of sqlite.

Re: Alternative player ranking system

Actually, Raonic turned it after his 3rd round match against Troicki, but difference did increase after Simon/Wawrinka also. Troicki had a good run until that loss, he was almost equal with Raonic points wise at that time.

Re: Alternative player ranking system

Raonic past Djokovic? I guess the latter lost quite a bit from the Simon match, Simon being very far down the rankings. Whereas Wawrinka will have been worth more as an opponent having already seen some success in 2016.

Re: Alternative player ranking system

Into the quarterfinals Raonic is leading the race with 124.1 point, Djokovic second with 121.3, folowed by RBA, Ferrer, and Federer at #5.
Combined "weight" of the players from the top half of the draw is 398.4, and bottom half 388.2, which is quite balanced, but also expected since the tournament itself contributes majority of the points at this stage in the season.

Re: Alternative player ranking system

You wouldn't believe who is currently leading the Elo race after the 1st round matches finished at the AO!
It's Roberto Bautista Agut with 82.9 points, in front of Djokovic with 75.6, and Troicki with 75.5.
But it's Djokovic who has the best points per match average, 12.6.

Re: Alternative player ranking system

I'm able to put the week 2 update early, thanks to pre-AO tournament scheduling and time zone difference.
RBA snatched the #1 from Djokovic, but we'll see how long will that last Troicki again having a very strong run at the start of the season, and I'm looking forward to see how long will that last My personal honorable mention - Jack Sock, but he may have overdone it already so early in the season.

Re: Alternative player ranking system

Some bugs surfaced where I didn't expect them, especially after 3 full years of implementation. I had to deal with them before I was able to compile and publish the first update of the season.
So, here it is, ranking after Abu Dhabi Mubadala exhibition:
Code:
"Race" Positions                             Elo    Matches  Last match
rank   moved     Player                      points played   date
  1      n/r     Rafael Nadal                 24.8       2   2016-01-02
  2      n/r     David Ferrer                 22.8       3   2016-01-02
  3      n/r     Milos Raonic                 11.2       3   2016-01-02
  4      n/r     Kevin Anderson                0.4       2   2016-01-01
  5      n/r     Stanislas Wawrinka          -10.8       2   2016-01-02
  6      n/r     Jo-Wilfried Tsonga          -12         1   2015-12-31

Re: Alternative player ranking system

I would normally put an update from the Mubadala exho last week, but I was on vacation skiing in Borovets, Bulgaria, and my database resources were limited
Both updates (previous and this week) coming soon..

Re: Alternative player ranking system

Based on this analysis, if I was to implement the idea of using games/set coefficients instead of always treating sets as 1, I would have to modify the K factor to somewhere in the range of 36-40 for the Bo3 format instead of current 24, and in the range of 55-60 for the Bo5 format instead of 36, averaging at 38 and 57 respectively. I also analyzed only matches in the Bo5 format separately, but the result was almost identical.

Re: Alternative player ranking system

The discussion with Litotes made me curious to actually find out what is the most common result in games per set. I accumulated over 8300 matches so far in my database, with over 22000 sets played. So, here is the result (top 10):
Code:
Setscore    cnt
================
6-4         5309
6-3         4988
7-6         3841
6-2         3146
6-1         1949
7-5         1825
6-0         516
3-0         29
1-0         26
4-1         24
As it was expected, the 2 most common results were 6-4 and 6-3, followed pretty closely by tie-breaks. 6-4 and 6-3 most often represent sets with one break of serve. Interesting fact is that breadsticks were more common then 7-5. After the 7 regular outcomes of sets by the tennis rules, we have next 3 that are the consequence of retirements. So, retirements have been most often done at the results of 3-0, 1-0 and 4-1.

There was 49 sets (deciders in the Bo5) that were played for the differential, most common of them being 8-6 (16 such sets), followed by 9-7 (9), and 10-8 (8).

Aha, thanks for the clarification! Again, no such thing in tennis with a tree structure of the competition.

Nevertheless, I was aware that I couldn't literally translate the system from chess to tennis Thanks for the explanation!
