Player Match Ratings

I'm just curious to why these are low when you are winning/won a game? I'm gettin 6.0 - 7.0 when i win a game 1-0,2-1,2-0 ect. I only get very high ones if i win 4-0.. But the thing is the ones where i score less i am watching them and i am dominating those all of the time?

It is just a little disappointing when i see the low match ratings when it don't actually show how well the player did in the match(if you watch the games).

I don't like the player rating system entirely, but i think it is as good as it can be i think. Because, on newspapers rarely will a player get man of the match and good ratings without scoring or assisting, but, sometimes, eg Makelele would get high applaudits for doing neither, yet a performance of that calibre on fm would only receive around a 7.0 depending on result.
