Done! I've put the new and old stats in for ease of comparison. It doesn't change a huge amount; repeat winners increase by 10%, new winners decrease by 10%, debut winners decrease by 20%. (Therefore new winners whose story is
not their debut increase by 10%.)
Entries before first win for all winners:
Total wins and total entries for contest winners:
Regulars who have not yet won a contest:This didn't change
at all. Every single person who entered five contests or more before
@xiagan took over won at least once.

Probably due to the low number of entrants more than anything else.
So, stats remain the same: 242 total entrants, 47 have entered 5 contests or more. 14 have not yet won (30%).
