Basic arithmetic errors in chess.com app

I don't see how I can share a screenshot here, but basically according to chess.com I've had 2812 wins in the last 5773 matches, 2816 loses and 145 draws, however 49% of my games are wins and 48% are loses, even though 2816>2812. I'm not trying to be annoying, this is unacceptable. Also lots of times the number of moves with grades in an analysis don't add up, even though grades are given move by move in the review. If these kinds of mistakes are made how do you deal with Elo inflation for example? What are your methods for detecting cheating?? I used to get lots of points back from chess.com because some of my opponents were cheating. Not anymore, why? Did you change your cheat detecting algorithm?
