From what fights has this data been gathered?

Neo. No matter than percentile average, Dark Knight represents only 22% of uploaded parses. Now this isn't a full proof metric. Samurai, for instance, has high upload totals despite slowly losing its foothold while Machinist is the lowest despite being meta. Still, it's far better than looking at a WF clear and assuming everything is fine.
