I compared your Florida Rankings, to my
World Rankings, and found several discrepancies. Your method sounds the same, normalize to 12 matches and double if only 1 event, so the results should be comparable. Many point values were 1 point off, and a few are 2 points off, which are probably rounding differences.
3992: I have 60 points, 10 draft, 0 elims, 7 wins (normalized to 7.5), 5 awards x2 since they only played one event.
3556: 1 have 58 points, 10 draft, 0 elims, 8 wins (normalized to 9.5), 0 awards x2 since they only played one event.
4224: I have 16 points, 4 wins (normalized to 4 wins) x2 since they only played one event.
