[BF3] Why are there players who leave the game with very good results without saving their record?

[BlackCell67]

I have a question, I would like someone to help me. Why does this player, after having a performance of 160 to 54, leave the game without waiting to save his results?
He always does it, why?
He kills in a very easy way.
He is very good?

I was told long ago, that high level players used to leave matches just before the end to avoid server stats being saved, but EA patched that "feature" long ago, and alot of folks got in the habit of leaving early, and after EA patched this, they still leave early out of "habit".
