The current leaders in the Big Gainer of the tournament awards are Mischa Zverev (+43) and Mirjana Lucic-Baroni (+60). Mischa is out of the Australian Open, but can still win the award if Roger Federer wins the tournament, otherwise the tournament winner takes it. In the Women's race, If either Mirjana or Coco Vandeweghe make the final, then whoever does better will win the award, otherwise Venus Williams will take it from Mirjana if she wins the title.
But before the rankings, some stats I calculated for the top 150 players:
| Men's Rank | ± ELO |
| 1-10 | 70 |
| 11-20 | 65 |
| 21-50 | -1 |
| 51-100 | -68 |
| 101-150 | -39 |
| Women's Rank | ± ELO |
| 1-10 | 8 |
| 11-20 | 38 |
| 21-50 | 17 |
| 51-100 | -77 |
| 101-150 | 56 |
Now we're at the semi final stage, I'm also going to add some prediction percentages for the final and the title, based on these ratings.
