Dont mind the perfect game, it was only a 15-move blitz game that I played almost perfectly in

So in the game review, at the bottom is tells you what rating you played at, does anyone know how they do that?
My blitz rating (thats the format this game came from) i was rated 816

If there are less moves. There are less things to calculate. But if it was a longer game then there are more calculation that may give a less rating.

I guess that is maybe it was just a 15-move game?
