===How does "MinorSuperficial article edits marked as minor" work?===
All article edits marked as minor count as minor (reverts too). This takes (all minor'''superficial''' article edits) - (articlethose editsnot changedmarked toas minor) and divides it by (all minor'''superficial''' article edits) to get the percent. Note that superficial edits count as minor as well here.
Note that while reverts are changed to minor for other stats, they still count as whatever they where marked as.
Edits with no summary that are marked as minor are still counted as minor.
