I'm 144 in the official rankings, but 145 in yours, even though I have 429 points in both. Also (don't know if that matters), Antalya is written as a Challenges when it's in fact a Futures tournament.
Well, at least you have the same points, that means your points are correct. The problem is that someone above you has extra points. I have to see who it is and, the most difficult, check which tournament is wrong.
The fact that Antalya is marked as Challenger and not Future doesn't change anything because the points given are the same.
I have 50 pts in official ranklings and 47 in yours. Still, quite interesting and I hope you can keep it up through the next season, great idea.
Ohh, and do you know which 3 points are missing? That could be the key to fix other point breakdowns.
