Systematic fixing by the ATP Tour
is it some quantum physics puzzle ?
Lousy database stored procedures, scheduled jobs and flaky DBAs (Data Base Admins).
Obviously, since neither player won on Sunday, the system rewarded both players with a "Loss" and the points one receives by making a Final without winning it.
If one comes into the web site as a Rafa fan, his player loses to a "Djokovic"; and if a Nole fan comes in, he sees his player losing to a "Nadal". But then they see only empty stats.
It looks like the DBA has cleaned up the mess as of now.
The erroneous data is gone.
