I recently changed the email associated with my account and the last 60 day stats & best ten days stats for the day of the change and prior are zeroed out. all the credits are there and my rank is where I'd expect it to be so no foul, I just didn't expect it. I know an email change is likely to be a rare event but I was just wondering if anybody else had seen this behavior. The statistics page has also reset (makes sense) so all my trend history back to 2009 is gone as well which is a little annoying.
