Actually, there ar two different check counts:
- Your total amount of checks.
- Your amount of checks of movies currently in at least one top list. This amount is always less than or equal to the first count.
For the top users chart, only the second count is taken into consideration. Therefore, to rise in the charts requires you to go see movies that are in at least one top list at the moment. Please note that sometimes movies you have checked disappear from a top list, thereby lowering your second check count but not your first. Should the movie re-appear in a top list (not necessarily the same one), check count #2 will be incremented again.
