If you go all the way to 38, it would provide some ground to a rewrite of the outdated “38 basic josekis” (Ishi press).

Would ot be a huge different if we only look at Japanese players’ games? korean players should contribute the most for the high percentage of 3 3 joseki

What’s the source of the database? 101Weiqi, GoDB, Go4Go, GoGoD, GoKifu, Web2Go, Sina, what?

You never gave a source for your 2019 database either.

Only KifuDepot/Go4Go this time.

2019 also included Sina, GoKifu, Fox broadcasts, and Korean Baduk league website.
