did some typing for fun earlier and got some pretty dang good results, 453kpm for japanese and 603kpm for english, both staying at 95%+ accuracy :D
been actually super into typing recently for some reason, dont think this is the end of what im trying for. might eventually try for 500kpm jp or 700kpm en idk who knows weee
this is the program i used btw https://denasu.com/software/weathertyping.html
has english built in and works for english and japanese, with support for custom word lists and ALSO online 1v1 races with those custom word lists, which is pretty dang cool
