Another way this site is acting strange

A few days ago my overall total of wins and losses struck me as weird. I was several games below .500, when I was certain at my last login I was several over .500. And the totals were in the 90s, which looked weird because I could have sworn they were in the 80s. Just now I went through the effort of counting my history. According to that, my record is 86-83, which goes along with my recollection. But covers has me as 95-97. The only way in which overall record matters is in case of a tie among monthly leaders, in which case the system giving me 9 more wins can only help. However, I'd much rather A. that the system not be capable of such an error because if it is then it is capable of other errors and B. that I as a matter of personal pride have a record above .500 rather than below .500 . It's embarrassing enough that I took GS -4 and they lost by 39...
