The Graph

[yorikiried by fate 1,989]

So, proper correction for my point about many Ozeki demotions within a short period of time:

In 2019, we had 3 demotions but 4 demotion constituting events (Takayasu's second consecutive MK at Kyushu which will lead to his demotion for I/2020). So going back to 2017, we saw/will see 6 demotion triggers between I/2017 and XI/2019 or 6 demotions between III/2017 and I/2020. This is a span of 18 basho or three years (-> 0.33).

The previously most dense phase was 3 demotions between I/2000 and IX/2000, though the year had only two trigger events as Takanonami had his second consecutive MK at Kyushu 1999. But with events in 2001 we reach 5 demotions between I/2000 and IX/2001 (the triggers being between XI/1999 and VII/2001). So the span back then is 12 basho (-> 0.42).

Another trivia thing that I just now happened to have simply counted out with the help of the visual timeline is Ozeki yusho droughts (spells of consecutive basho without Ozeki yusho). Turns out we are in the midst of the second biggest one just now.

Ozeki yusho droughts (10+ basho) since 1958 [in very pedestrian format as no-one bothered to answer my how-to-make-tables-these-days question that I posted a few months ago...]:

1. VII/77 - V/81 -> 24*

2. III/17 - ?          -> 17+

3. III/70 - IX/72  -> 16

4. III/65 - I/67    -> 12

5. VII/09 - V/11 -> 11**

6. XI/61 - V/63  -> 10

6. III/88 - IX/89 -> 10

6. VII/99 - I/01  -> 10

6. V/14 - XI/15  -> 10

 

* These were insane four years of Yokozuna dominance (initially Kitanoumi & Wajima, then Wakanohana II & Mienoumi on the way; both of the latter pair were promoted without a yusho win in their Yokruns). The sole non-Yokozuna yusho in the spell came in basho 22 by the hands of Sekiwake Chiyonofuji who finally broke the drought three basho later as Ozeki.

** 10 if you discount the hon-basho-hood of V/11, the infamous Technical Examination Tournament. For which one can surely argue, as Kaio for instance certainly chose not to end his career there (picking up a totally epic and absolutely non-orchestrated final Yokozuna bout win instead [in his final Tokyo bout, in the last bout of the basho]).

I don't know about Takayasu's prognosis to know how realistic it would be, but it would be hilarious for the above streak to continue if Takayasu gets his first yusho next basho.

Thanks for this great visualization!  Noting the bottom part of the graph is relatively sparse in recent years, I was wondering if you would consider adding the "dai-Sekiwakes" Tochiozan and Mitakeumi and perhaps Miyogiryu, Tamawashi and Ichinojo (8 bashos at Sekiwake each)?  Just a thought.

Firstly, you're welcome.

The bottom part usually fills up with delay, as entries back in the timeline are added with any new Ozeki promotion. So assuming, whatever, Asanoyama will reach the rank, there will be a couple of entries added further left (i.e. his debut, his sektitori and Makuuchi debuts, plus his most recent Komusubi and pending future Sekiwake debut).

I love the yearly Graph update, thank you. I think I love the Graph because it is something really highly technical and full of data that is also probably only truly appreciated by a handful of people on the planet but is, in fact, an absolute piece of art. Kudos to you.

Ist es schon wieder soweit?

 

Hello world. The updated Graph awaits your embrace and praise.

New features:

• Asanoyama's promotion made it necessary to introduce a new color to indicate Sandanme tsukedashi hatsu-dohyo.
• The onslaught of improbable Maegashira yusho gave me the idea of indicating the exact rank in the vicinity of the respective champion's name.

 

Comments (oh so many comments...) more or less derived from the visuals:

• The Graph's top is punctured! With the Kyushu banzuke, the active champions' cumulated yusho reached 61, which is a new all-time record and one more than my vertical grid tolerates. In fact, the previous record of  XI/19 was improved four times throughout the year. What we need is for Hakuho to retire... Anyway, we have the yusho experiencest group since ever.
• With the Kyushu banzuke we also saw 11 active champions, which ties the record of VII/2000, right after Kaio's debut yusho. Back then, the crowd was reduced to 9 after only two basho, when former champions Kotonishiki and Mitoizumi retired. It's nice to see the two lists of 11 champions next to each other. Then: Takanohana (20 yusho at the time), Akebono (9), Musashimaaru (7), Takanonami (2), Kotonishiki (2), Mitoizumi (1), Chiyotaikai (1), Dejima (1), Musoyama (1), Takatoriki (1), Kaio (1). Now: Hakuho (44), Kakuryu (6), Mitakeumi (2), Terunofuji (2), Kotoshogiku (1), Tochinoshin (1), Takakeisho (1), Tamawashi (1), Asanoyama (1), Tokushoryu (1), Shodai (1).
• The number of foreigners on the banzuke decreased again. In September and November the overall figure was 28, which is the lowest number since XI/2000.
• In January, March, July and September there were only two sanyaku foreigners (the Yokozuna) on the banzuke. The last time this happened before was in IX/2005 with Yokozuna Asashoryu and Sekiwake Kotooshu, who ended up deciding the yusho in a play-off. Guess who won this contest of mental fortitude...ahem...
• Talking of play-offs while they are fresh: the November basho gave birth to the first Ozeki-Komusubi play-off. Komusubi are widely underrepresented in play-offs throughout recorded history. Terunofuji was only the fourth Komusubi participant. Previously Yokozuna Chiyonofuji beat Komusubi Asashio in V/1982. The same pair (with same ranks) also fought it out in XI/1981. With the same result. The only time ever a Komusubi won a play-off was in XI/1974, when Kaiketsu beat Yokozuna Kitanoumi, none less! As for play-off participants' ranks since 1958: Y (74), O (42), S (20), K (4), M (10).
• In Is-That-All-? news, Hakuho managed at least one yusho win for the 15th consecutive year. Nevertheless, 2020 was the first year since 2006 (when he won his first yusho) with him only getting one and not at least two. The next best are btw Taiho (12), Chiyonofuji (10), and Kitanoumi (9), which is the most unsurprising rank 2 to 4 list ever. It has been reported, though, that Asashoryu is still winning yusho from his home office.
• The Maegashira...Of course two yusho from the lowest nominal rank are exceptional, but since the Graph doesn't inform us about the division size and such, I will not go further into that. Combined with the win of Asanoyama in 2019, Tokushoryu and Terunofuji made it 3 out of 7. If you go back to Tochinoshin you have 4 out of 15. But this is only the second highest density of Maegashira yusho. In 1991 and 1992 we saw a spell of 3 out of 4, or 4 out of 7, respectively. Back then it happened around the intai of Yokozunae Chiyonofuji, Onokuni, Asahifuji and Hokutoumi, culminating in the Yokozuna-less time between VII/1992 and I/1993.
• Maegashira II: Oh, btw the rank has won the year. Even better, the rank of M17 has won the year: 2x M17, 1xY, 1xO, 1xS. Unprecedented, of course. This is only the 9th time that the rank of Yokozuna didn't win the most yusho in a celendar year or was at least tied for the lead. Previously: 2012 (3xO, 2xY ,1xM), 2003 (4xO, 2xY), 1998 (3xO, 2xY, 1xM), 1995 (5xO, 1xY), 1992 (2xO, 2xM, 1xS, 1xK), 1972 (2xS, 2xM, 1xY, 1xO), 1969 (4xO, 2xY), 1961 (3xO, 2xY, 1xM).
• Finally, the Ozeki yusho drought has ended. Officially at 21. This is the second longest drought after VII/1977-V/1981 (24). Personally, I think that we have a new record at 38, since...never mind...figure it out yourselves...

 

The link is fresh for two months. If you need the file after that, give me a shout.

See you around.

Tamawashi and style and drought (jeez...); also "just one" yusho for Hakuho in 2018

The Graph is too powerful for my computer and I love it. :D

[Sue 483]

Do the experience and number of different winners numbers count as of the beginning or end of the basho? Kotoshogiku's intai should affect the total of both, unless you're not counting him as intai until the next banzuke comes out.

Every instance in the timeline (horizontal direction) refers to the banzuke, so number of champions and experience level is given as for the members/entries of the respective ranking.

That being said, the yusho winners' entry directly under the graph extends this somewhat, as it indicates the winner of the basho that has been played out based on the respective banzuke.

Does the makuuchi experience level account for Terunofuji's demotion/repromotion?  It's an aberration, I know...

I don't quite understand. Are we talking about Makuuchi demotion and repromotion?

In that case, there is a summary of this particular topic right on page two of this very thread, which relates to an exchange in an older hon-basho thread, that started around here. The summary has not been updated, though.

Or glasses (though mine seem to try their best from preventing me seeing anything at monitor distance...).

Maybe I should add system requirements (man and machine)?

Well, firstly it seems like you were able to upload a screenshot. Do you have problems with the pdf? Its size is merely 3.5 MB so you shouldn't have trouble opening it and zooming in, as long as your PC is not older than , say, 15 years. If we are talking mobile devices, I won't be able to help, since I don't care much about them.

I had problems seeing the fine details opening it with Firefox; opening it with Adobe Reader made everything as crisp as it should have been.

Opening PDFs in FF is a crime in itself!

But seriously: thanks for pointing out that usecase. I hope people will take note.

@Off-topic: Seems to be a severe case of wintenitis. I had several similar support calls  where PDFs suddenly opened in the browser by default (not only FF), although Acrobat Reader has been installed.

Interesting. I have something similar, as of very recently. PDFs suddenly opened in FF as default, like you said, instead of -- in my case -- Acrobat. I could switch that back, but then the PDFs suddenly were shown to be downloaded before opening. After the session was ended, these downloads dissappeared again. So some glitch in the temporary file handling, I suppose. This MO just got lost after a couple of days for no apparent reason. Now, every PDF gets downloaded for real and I have to open them manually. If it really is a W10 thing -- as your experiences suggest -- this would be highly annoying.

If I would have to take support calls regularly (and not just from my parents), I'd run amok after 15 minutes, btw.

OT is cool, since it's my thread.

[yorikiried by fate 1,989]

Question:

Since the issue of former champions competing outside of Makuuchi came up at two different points in time already, shouldn't it be visualized?

I think I could extend the meaning of the "Absent former champion" thin graph line to include guys in Juryo and below. Addtionally I could add a counter under the side line points to indicate the number of absentees (for reasons of kyujo or being aoutside of Makuuchi).

Does anyone have an opinion?
