Kachikoshi

You marked Kinbozan as having a losing record but he actually had a winning record.

I’m in as a newbie.

I only found one error: In 1914, the tournament was only 10 days.

That wasn’t even a real makekoshi; it was a forced COVID withdrawal when he was 7-3 (and so likely en route to another kachikoshi). His last real makekoshi was November 2021.

Gonoyama has now received a walkover win in three consecutive tournaments.

This has only been true since the early 2000s. Before then it was standard for newly promoted Ozeki to go above kadoban Ozeki. Sometimes newly promoted Ozeki would even be promoted above Ozeki who had earned (weak) kachikoshi in the previous tournament. Here's the last example of this occurring that I could find: https://sumodb.sumogames.de/Banzuke.aspx?b=200009. IMO it would be better for Kotonowaka to be ranked above Takakeisho next basho. Otherwise we could end up with the bizarre situation where Takakeisho has a better record than Kotonowaka but gets demoted to Sekiwake while Kotonowaka doesn't.

In some sense he was fourth in line because he computed ahead of Bushozan by the raw numbers (admittedly, not promoting someone at 10-5 from Juryo 3 is pretty harsh).

My guess is the overall rate counts only the period when the given rikishi was active.

It's so inconsistent that I wonder if it's actually just random.

How do banzuke tiebreakers work in this game? In particular, I'm confused how tiebreakers worked for these four players for the Kyushu basho. All four were tied by standard banzuke math, but they ended up ranked in this order: Hinomaru, 5-10 from West Makushita 47 Clementesan, 9-6 from West Makushita 55 Toshishugisha, 8-7 from West Makushita 53 Shokoki, 2-13 from West Makushita 41 I'm wracking my brain trying to figure out a rule that would produce this ordering.
