I have to admit that I felt kinda "offended" at first about it being possible that someone scores so high despite handicapping himself to 3 picks.
Looking over a couple of those games, as expected I saw pretty strong play and some luck. However, as a third factor it seemed to me that also some opponents handicapped themselves.
With some opponents it was not easy to spot and I might accidentally insult them if they played serious:
