I forgot about this, but crunched the numbers. Final results:
1 (tie). El Dude, don fabio 14 points
3 (tie). tented, Nadalfan2013 11 points
5 (tie). Moxie, Iomaha 10 points
7. shawnbm 9 points
10 (tie). Phileaglesfan, AntiPusher 8 points
12. attamole 7 points
If I do something like this again, I'll have to make a simpler scoring system as I had to do everyone several times to make sure I got it right.
More interesting are the trends of what people missed, namely no one picked Jannik Sinner to finish #1. I originally did but backed off at the last moment. Oh well. But he was certainly the most underrated. Also out-performing our collective predictions were Zverev and Fritz, maybe De Minaur.
Players that were overrated to varying degrees: Shelton, Rune, Nadal, Hurkacz, Tsitsipas. Some expected Arthur Fils to take a bigger step forward than he actually did. Maybe next year.
