I compiled a database of my last 6,000 Bang! games on BGA and made a short video about the results.
Main numbers:

In the video, I go over:
representative win rates by role
some of the more meaningful hero win rates by role, especially for Outlaws
how Outlaw seat position relative to the Sheriff affects win rate
Full details are in the video (ENG SUBS) https://www.youtube.com/watch?v=5hGj7c2rHEY
UPD #1. Added stats, when we got 1v1v1 situation (by math we pretend for the 33% wins here for each role)

UPD #2. Added stats: sheriffs winrate, based on vice death (from our vice and sheriff perspective)

UPD #3 Added stats: outlaw winrate changes in specific situations

UPD #4. Added stats: Renegade checkpoints

UPD #5. Store value
