There is a web page that we sometime see on NHKWorld's sumo program that looks like spreadsheet page with the old new banzuke side by side, with red and green arrows indicating who has gone down/up. Can someone remind me how to find it please? TIA
I built a browser tool that ranks rikishi by wins over rolling periods (last 1 basho, 6 basho, 60 basho, etc), with division filters and alternative views.
Context: How interesting or useful are chii? Yes, ... ancient and noble history ... samurai tradition ... etc, I get all that and it is part of what I like about sumo. But from a completely objective perspective? Not so much, I think.
So here is my take on what you get if you focus on the number of wins. I am not claiming anything other than it reveals interesting facts like Asonayama is joint #1 (with Asahakuryu) from a certain perspective. I am not claiming that Big A (as we call him here) is the best in any important way (although he is very clearly the best ever sumo wrestler and will become ruler of the world quite soon).
I have done my best to take into account reasonable thoughts about what data to present. Some ideas (such as to allow the date be anything other than the last basho) are on the wishlist. Others like not counting fusensho as "real" wins don't seem that important so I didn't bother. Stats such as standard deviation are easy to add but probably pointless.
I will also add that I am aware you can get weird results if you don't think about the settings you select. Eg looking at the results for Jonokuchi over the last 10 years will not tell you much I think (apart from the fact there are people who have been in sumo for 10 years and are in Jonokuchi).
Very happy to consider ideas eg divide number of wins by BMI?
