Strength of Yūshō

Recommended Posts

Posted (edited)

I'm sorry to present yet another inane stats thread with no real thesis, but this doesn't contain as much writing, I swear!

While I'm on the DB scraping train, I've put together a table displaying yūshō scores since 1950, together with their sum of opponent score (SOS), to provide some sort of means of assessing yūshō. Some yūshō were less gimmes than we thought (they might still have been based on rank). For instance, Tokushōryū's makujiri yūshō in Hatsu 2020 had a SOS of 120, definitely above average for yūshō. Conversely, Hakuhō's last yūshō in Nagoya 2021 had a SOS of 97, pretty low, and considering how shaky he looked that basho, having slightly tougher opponents might well have handed Terunofuji the Emperor's Cup instead. Some of Takanohana's yūshō were also very cheap, unsurprising considering what we know about the circumstances of the joi at the time.

Overall, the vital stats are as follows:

For those who want to screw around with the data in raw normalised form yourselves, the GSheets link is as follows: https://docs.google.com/spreadsheets/d/1cZXTA90Q95L9qmfex4IJ20LlsRZam3GcaLD26Nsng0M/edit?usp=sharing. There's a lot of follow-ups possible, like which yokozuna averaged the highest strength of opponent schedule, which yūshō that led to promotions were cheap, etcetc, but we'll see what comes up in reactions to this.

(Also as an aside in case the DB folks are looking - yes, the 1 page/s rate works fantastically. Very few access errors if at all.)

And lastly, the table:

As you point out, rank should make a difference. An opponent who ends up with a score of 10-5 from M14 is probably not at the same difficulty-level as an opponent who scores 10-5 as an Ozeki.

Furthermore, by doing really well a rikishi would lower their SOS. Let's say in a basho that the Jun-Yusho line was 12-3 when the yusho was 15-0. Instead of going zensho, the yusho winner could have gone 12-3 with a playoff win instead. That's three more wins for our winner with a zensho, but three more losses for his opponents (and consequently a lower SOS for our yusho winner).

Given that you are disregarding rank (reasonable, since a highly injured Ozeki or Yokozuna may not be the strongest opponent one would have to face), then I would suggest a slight modification. Give something like 2pt for a win, 1pt for beating  rikishi with double digits and 1pt for beating a rikishi with at least 13 wins. So a yusho winner who beat a 14-1 rikishi would score 4pts for that victory (win + double-digits + at least 13 wins). You could also subtract 1pt for every time our yusho winner beat a rikishi who had double-digit losses, or similar. So beating a 5-10 rikishi would net you 1 point instead of 2.

Furthermore, by doing really well a rikishi would lower their SOS. Let's say in a basho that the Jun-Yusho line was 12-3 when the yusho was 15-0. Instead of going zensho, the yusho winner could have gone 12-3 with a playoff win instead. That's three more wins for our winner with a zensho, but three more losses for his opponents (and consequently a lower SOS for our yusho winner).

If I understand my sources correctly, the way to sort this out is actually to do a full Buchholz scoring by multiplying by the rikishi's own score. The current method is really only suited for tiebreak purposes - i.e. comparing scores of the same number where that multiplication wouldn't make a difference. However, that's a lot less intuitive to look at, so while it would appropriately differentiate the zenshō from the 12-3 D by showing an increase in the SOS by 25%, it would be less easy to use that number straightaway as a means of comparing opponents. It would more accurately reflect how impressive the yūshō was in terms of the opponents beaten and the score eventually achieved.

As an aside, I know from my brief dive into said sources regarding ratings that there are a lot of different systems out there each with their own strengths and weaknesses. Any others that might be relevant at this point?

I would take a 2 year window of results for each rikishi for the basho in question, and calculate the decayed history rating for each. Then the strength of yusho would just be the average decayed history rating of defeated opponents. This would take into account situations where lower makuuchi is pretty strong just by luck (some guys from joi sitting out due to injury in previous basho plus some young star coming up from juryo or something) that would be obscured by using just rank or SOS.

Decayed history rating did pretty well at the various sumo games - better than I did with my own brain (though I'm kind of dumb just fyi)

Yeah, not accounting for opponents ranks at all won't do. If one wants to calculate strength of the opposition which does not have any Y or O among them, I'd say just look at their positions at the next banzuke. Of course it's not the case when talking about makuuchi yuusho, but there are still some viable methods, e.g. just like counting for promotion/demotion purposes -  Rank+score.

There are many things wrong with this type of analysis.

First, when assessing strength of schedule in this way, you need to factor in to each rikishi's score their own win-loss record.  The main reason for this is to get around the effect of winning more meaning that your opponents lose more.  The best way to do this is to ignore the matches the rikishi himself was in, so basically subtracting from the total the number of losses that he had.  You could alternately add his own wins to the total, but if you're looking at win percentage of the opponents, this skews it towards 50%, as it's counting a win and loss both for the matches the rikishi himself was in.

Second, it also doesn't really compare well when considering the effect of withdrawals.  Sometimes the withdrawal means the rikishi was hobbling coming in, but sometimes it means they got hurt during the tournament.  A Yokozuna who wins their first match but gets hurt in the process should be considered a better opponent than average, not the same as one that got only 1 win (See Harumafuji, Nagoya 2015).

Third, it's only really comparable when rikishi have the same sort of opponents, and the main difference you're measuring is in which rikishi were not fought because they withdrew or were the same heya.  It's not comparable when you have a mid-to-low maegashira in the mix, since their general grade of opponent is going to be lower. 

How would I improve this?  One way to measure the quality of the opponent would just be by rank.  If you wanted a source of points by rank, there's the RotoSumo schedule of points per win by rank readily available.  I'm sure it's not perfect, but it's a start.  Another would be to do a ratings engine and get some measure of how strong each rikishi is that way, and then measure the expected wins for a rikishi of constant quality against the winner's slate of opponents   The problem with ratings engines (besides the work that goes into building one) is that they are prone to either deflation or inflation, as their main goal is to rate players against their contemporaries, not against their predecessors, and it's impossible to know whether this inflation is due to a real increase in strength or just a fluke of the rating system.  You could normalize the ratings every so often, but that forces the assumption that average strength never changes.  At best you'll be able to see which Yusho were relatively harder or easier compared to those surrounding them, though it wouldn't necessarily work comparing Yusho from decades apart.

It is a complicated thing.
First you look at the opponents results to get SOS.
But then one opponents 9-6 is not the same as another persons 9-6 so how to diffrentiate?
You could look at that person's opponents SOS to weight the input but it seems like a vicious circle.
Plus we haven't then taken into account the issue of feedback error [aka double counting] because the initial persons's reslut is in a sense double/triple counted.
Then should we also consider rank not just results alone but that opens up another can of worms about people struggling with injuries etc.
Ultimatley we have to accept that there is no one true method.
Whatever method we choose it is a matter of choice/opinion about what is apropo.
Still it would be interesting to see the results of these studies to help us to make our choices.
We just shouldn't see it as ultimate proof.

Anyone remember the old Sumo mailing list from the previous millenium? (Scratchingchin...)

Off topic, but I have just read your tagline. Not only do I remember the old Sumo Mailing list of the previous decade, I am still on it - and yes, there is still traffic - but nowhere near what it once was.

Ironically I dropped off that list back then because I was far out of reach in various parts of Japan for an extended period without access to online.

About a year ago I started one of many unfinished projects, looking at the "strength" of a basho in terms of career high ranks: that is, not only the Y's and O's, but the future Y's and O's and S's, etc.  Obviously, you can't do this for this year's or last year's basho, but you can go back, say 10 years and find out (in retrospect) what an awesome batch of career-wise awesome wrestlers were present at that basho.

I am out of town and working on other things right now, but I remember clearly that the most awesome basho, going back to ~2000, was the Natsu 2008 tournament won by Kotooshu (go figure!).  I will attempt to find my spreadsheet in a week or so when I am back in town.  IIRC I took career high ranks and then awarded points for Yokozuna (10), Ozeki (8), etc.  That sounds like the SOS approach you may be talking about here.

Someday after I retire, I may finish all these projects and post them as a set.  That should scare away a good number of forum members.(Sleeping...)

Going by career-high rank, I count 5 yokozuna and 4 ozeki on his fight card. And his only loss was to Aminishiki.

Retirement is a good starting point for all those projects that have been sitting on the back burner.  Those projects lead to new ones.
