Re: Alternative player ranking system

I decided to run a calculation of rolling Elo ranking, purely as a control measure, as it should be equal to the race ranking at the very end of the season. It turned out that there were some differences, mostly around 0.1 Elo point. At first I attributed this difference to the fact that I use different databases (sqlite for race, and mysql for rolling ranking calculations), but on closer inspection I found one larger difference regarding Donald Young's points. It seams that the recalculation of the race ranking which I had to do couple of months ago wasn't done quite right.

Anyway, here is the final rolling ranking update, which should also be the same as the correct race Elo ranking.
Code:

You'd never guess Del Potro was ahead of several multi-slam winners or that Becker was ahead of Sampras (or maybe you would, I know I wouldn't).
Or Murray's peak higher then Connors' (!!!), Becker's and Sampras'... Just shows his tough luck. On the other hand, with some lighter competition he might have never reached a peak this high. That might be the case with Sampras. Let's not forget that the higher the Elo ranking of the opponent, the more points is awarded for beating him. You cannot have a high peak without at least a duopoly at the top. I've always been saying - it's not who you have to beat at the bottom, it's who you have to beat at the top.

As for Becker, when he arrived, he absolutely stormed the scene - Boom-boom Becker

Interesting to note - of the Top 15 highest peaks, 1/3 was achieved in the last 10 years, including Top 2, 3 out of Top 5. Although '84 - '94 period was more "productive" in quantity.

Some of the most interesting facts:
- Del Potro has the highest peak behind the so called "Big 4" - a lot higher then the tripple GS winner Wawrinka who is at #10 (althouh he reached it way back in 2009, obviously his best year).
- Wawrinka's peak is lower then 4 other players who never won a GS - Ferrer, Nishikori, Tsonga and Raonic, in that order (they all were a GS finalists, though).
- Thiem has already reached quite high Elo peak rating (#12), just 2 places lower then Wawrinka, but already higher than the GS winner Cilic who is at #14.
- Half of the Top 10 on the peak Elo rating list reached their peak in 2016 (Djokovic, Murray, Nishikori, Raonic and Wawrinka), and 7 out of Top 20 (+ Thiem, Kyrgios), so it cannot be said that the competition is dead, even in (relative) absence of Fedal this year.

You'd never guess Del Potro was ahead of several multi-slam winners or that Becker was ahead of Sampras (or maybe you would, I know I wouldn't).

Re: Alternative player ranking system

I browsed a bit through the TA's Elo ranking list, and found it interesting to sort it by peak Elo rating.
Some of the most interesting facts:
- Del Potro has the highest peak behind the so called "Big 4" - a lot higher then the tripple GS winner Wawrinka who is at #10 (althouh he reached it way back in 2009, obviously his best year).
- Wawrinka's peak is lower then 4 other players who never won a GS - Ferrer, Nishikori, Tsonga and Raonic, in that order (they all were a GS finalists, though).
- Thiem has already reached quite high Elo peak rating (#12), just 2 places lower then Wawrinka, but already higher than the GS winner Cilic who is at #14.
- Half of the Top 10 on the peak Elo rating list reached their peak in 2016 (Djokovic, Murray, Nishikori, Raonic and Wawrinka), and 7 out of Top 20 (+ Thiem, Kyrgios), so it cannot be said that the competition is dead, even in (relative) absence of Fedal this year.

Re: Alternative player ranking system

I have to correct Litotes on one point. He said that I use sets as a ranking event, which is not exactly true. Rather, I use sets as a, how shell I put it... as a sub-units. For example, in chess there are 2 possible results for a match, a win/loss and a draw, so in case of a win, winner is assigned a value of 1 (for the purpose of Elo calculations), and loser a value of 0. The same can simply be applied to a result of a tennis match, with exception that tennis match can never end with a draw. That's the Tennis Abstract way, I suppose.

That's the main difference in my methodology. I use sets as a sub-units, so for instance in case of retirement of one player at a point where they won 1 set each, regardless who won a match in a sense of advancing to the next round, I will treat this result as a "draw" - they will both have a value of 0.5 in a Bo3 format, or 0.333... in a Bo5 format. Also, if one player lost a match but won a set in a Bo3 format, he will also be awarded 0.5 points.

One consequence is that, in contrast to Elo methodology in chess, the sum of points lost and points won by each player respectively, is not always 0 any more.

Thanks @Litotes for pretty much summing it up for me

I maintain 2 lists that are direct alternatives for ATP ranking lists - the "race" list where I count matches from the beginning of the calendar season, and the "rolling 52 week" list which is equivalent to ATP's official ranking. Tennis Abstract on the other hand obviously maintains what we can call the career ranking list, which I am not able to do, since I lack the complete matches database "since the beginning of time". My matches database starts with 2013 season, and I also recalculate the list covering the full period from 2013 till now. I'll post this list soon too.

Regarding methodology, Elo ranking allows for choosing arbitrary K-factor, and I don't know which value is used by Tennis Abstract. I already explained my methodology in full detail earlier in this thread. In short, I use the value of K-factor 24 for the matches in the Bo3 format, and 36 for Bo5 format. I also don't use any floor value for bias, and I don't know which value is used by Tennis Abstract. I can tell that during 4 full seasons peak accumulated points never went over 1000, and if we take into account negative points, total difference from the best to the worst accumulated to about 1100 points.

If they at Tennis Abstract use the same methodology as in chess, I suppose Litotes is much more qualified to explain it then me

Several differences, biggest are that Tennis Abstract treat every match as a ranking event, whereas G.100sic treats every set at a ranking event. And that G.100sic only considers the past 12 months whereas Tennis Abstract allows long term buildup. For them, Djokovic started the season with an incredibly high number and managed to stay ahead despite doing worse elowise this year (yes, he did). With nothing ever dropping off, a big lead at the start of a year makes it very likely indeed you'll stay ahead. Just imagine, if Djokovic were to go 0-20 next season (which I don't believe for a second, just giving a hypothetical) he'd still most likely be elo ranked in the top-3. Just as Federer has kept his spot in the top-3 since his big dropoff has mainly come from not playing matches at all, not losing them.

Re: Alternative player ranking system

Season 2016 officially over. Only 4 players involved in this week update, Del Potro finishing at #6 although he had a chance even for 5th place, but for that he needed a strait sets win over Cilic. He on the other hand had a chance to replace Raonic at #4, but with a loss fell short by just 0.5 points. Delbonis benefited 10 places and finished in Top 30, at #29 actually.

Rolling ranking update after WTF. Worth noting that Murray's numbers still include last year's DC final points (so do other's participants points). I discount points strictly on a 52 week window basis, unlike ATP.

While it's true that Elo (in this form, as I implemented it) doesn't take into account surface/environment specifics, as the events are grouped throughout the season, I don't think that specialization is that much rewarded over consistency. In case of Murray it has more to do with his really great patch of play over his closest opponent. Still wouldn't get where he is now without the great clay season. Also, let's not forget that he also played the most matches this year, 16 more then his closest follower in the rankings, which translates in accumulating Elo points.

Why couldn't Elo (it's Elo the name, not ELO the acronym, btw) be used for ranking? It is actually used in not so few areas. Any system is as good as it gets, and no system is perfect. It can be used as long it's used consistently.
