Not sure if I get this right, but it seems like I suddenly was bumped to 349.98 pts before today’s race. Please explain 
The columns are Before, Result, and Gain
Sounds like one or more of your earlier results turned into a pumpkin… I mean became over 90 days old.
Yes, I was about to suggest the Tour of New York might have something to do with it. You’re definitely not alone, my ranking just went up by 45 points as well 
Zwift has raised the bar 
I think it just removed some results - either results that weren’t races (like TdZ) or results that were 90 days old.
AFAK the race ranking points is calculated as
A riders ranking going into every race is calculated from the average of their 5 best results in the past 3 months . Zwift Power - Rankings
Mine should then be 237.49+378.81+351.38+318.80+292.27 / 5 = 315.75
Thx! 12/20 - 03/20. It was close 
I have completed a few races with rankings, however some of the results are not showing on my ranking profile and the best of 5 are also not showing the actual best results. Is there a way to refresh the profile to include all rankings?
I have learned that these questions can be sent to zwiftpower@zwift.com.
Refresh Profile button should update. Only best 5 from past 90 days qualify.
