The revert rate we use in our Key Product Metrics is problematic. Currently, it's:
Reverted edits (including reverted bot edits) / Non-bot edits
The definition was made under the assumption that bot edits are generally not reverted, but we've found that assumption to be incorrect.
In addition, we may want to consider only calculating reverts done in a set window after original edit. @nettrom_WMF has used 48-hour revert rate in Growth.
