Using rounding (rounded to 1000 total games played, 300 losses). You would have something around an 8.4k rating as you lose -13 on a loss and gain +12 on a win.
It's not actually bugged in how much rating you have, it's bugged because it's only giving you a flat value for every win or loss rather than a scaled rating. This means that you will always be able to determine the rating total correctly. Albeit, your starting rating could vary by a flat 600 difference, so the actual # is 8400+/-600
You're lying, and from your previous comments and actual knowledge of the game mechanics I doubt you could even get to a 2.6k rating in the first place.
Currently, we have some idiot on bastion with a 4900 solo rating, with over 500 games played and the record being something like a 5:1 w/l ratio which follows yours pretty closely.
