Took a crack at this earlier. the leader board is a little weird. seems to be like 2 real dudes and the rest are fake profiles. a Scores resetting on each new upload also encourages leaving changes unimplemented in the hopes of getting more battles over time.

The largest winner having 50 wins against 14 other opponents for instance). That guy adding a new script would instantly plummet down the leader board capping out at 14 wins again, Putting it below the 2nd place user.

The leader board will quickly become "who can have a mostly competent AI and never change it" over who actually has the better script.
