General DiscussionHow does dotabuff decide top 50 players on a hero??

what the hell is success if not winning?

who knows lol this is all it tells u "NEW:MEASURE YOUR SUCCESS HERO-BY-HERO
This new view added to the player hero summary page details which heroes you're most and least successful. It's an easy way to track your progress as you improve with specific heroes, or the strengths and weaknesses for another player."

Doesnt actually tell u how they come up with the %

I think it is still based on the extinct dotabuff rating

or something related to ranked/normal matches

once a wise man said "to know that you are good enough is more than enough".

If i'm not mistaken it depends on your mmr. The higher rating you have = the better chances you have to get into top 50.
