Someone told this already and I think it's pretty nice, but you should do this with various maps and not only one so people won't see you with 999999999 plays on a certain map
Play a map, edit the first notes to 300 and when you get 10k score edit the next note to get a 100
Then use Perfect mode and use replay player with that edited replay (10k score + "100" note), that way it will auto retry every time you get that hundred and still count the play
