2017 US Open Final Update

It's the final of the US Open, and we're about to crown the winners of the final Grand Slam of the year! But before the matches start, let's take a look at some stats I calculated for the top 150 players after the jump:

Men's Rank	± ELO
1-10	-8
11-20	-28
21-50	85
51-100	22
101-150	16

These numbers will change after the final as Rafael Nadal is obviously a top 10 player, and Kevin Anderson obviously isn't. The group which clearly did the best at this tournament are the 21-50 ranked players, led by Anderson, with Pablo Caarreno Busta, Diego Schwartzman and Alexandr Dolgopolov performing well. The losers are the 11-20 group, with most of them losing some ELO rating points, the major exception is Juan Martin Del Potro.

Women's Rank	± ELO
1-10	-34
11-20	72
21-50	18
51-100	-96
101-150	125

Unlike the Men's above, this won't change after the Women's final, as both Madison Keys and Sloane Stephens are 11-20 ranked players. That group did well, but the winners are the 101-150 ranked group, with Maria Sakkari, Kurumi Nara, Aleksandra Krunic and Jennifer Brady performing very well, and not many early losses. On the other hand, the 51-100 group disappointed here with many early losses, the best performers of the group were Shelby Rogers and Donna Vekic.

Now, my final ELO ratings and estimated percentage chances of winning:
