Tour of Zwift results over the line

When you finish a Tour de Zwift race, there’s a banner that says “You’re in the top X% finishers of Y riders!!! Congratulations!!!” or something similar. The math is grossly off. The number of riders (Y) is the total number of riders in all categories in the event, not only those in your category; and your positioning in % (X) appears to be calculated by dividing your position in your category, by the total number of finishers. Odd.

So I finished, say, 30th out of 90 in my cat, and got “You’re in the top 15% of 200 finishers!!!”. Because 30/200 = 0.15.

No wonder there are issues with distance remaining in events.
