Need help understanding results

My ratings say that the game is, say, 480th in humor. Which, by the way, makes absolutely zero sense to me because it's a goddamn Tetris variant. The concept of humor doesn't even apply here, not any more than ranks in (imaginary) categories like "Helps against malaria" or "Important for the middle eastern politics".

But anyway, it's 480th out of how many? All ~3k games in LD41? ~1k games in LD41 Compo? However many of those were rated (I guess something 700-ish)?
