Ahhh! I finally got around to checking the results just now.
Before making the GC picks, I thought the true final result should be the scores after the East and West finals; and that Points from the 10 Cup predictions wouldn't mean anything as they were just from a wild guessing game.
Clearly I was mistaken...
Thanks FlickeredFlame for doing this again this year, and congrats also to Thneed for almost tying for first!
