Before video requirements were a thing, at least half of the records posted to the rankings were fake. Maybe 5,000. This include fakes from players like Karl, Dark Avenger, ChodhE, etc.
Since the time videos were required UNTIL Everdrive became a thing in 2012/2013, about 500 videos were likely faked or spliced. This includes stuff like Jimbo's Silo 00A 1:34, Henning runs, and various Trent Hovis videos. Ace and Goose splices too.
I wouldn't put the Everdrive count to more than 50. If a player can get away with it on one level, they are likely to use it on multiple levels. Which is why anyone who votes 1 or 2 doesn't have a clue about anything. Assuming at least 3 people have managed to do this, which is a realistic guess, I would put the count to maybe 10-15.
