unfair point loss

i recently played a game. lost but had a fun time. when i looked down into the box i had lost about 20 points. "so"i said then looked at someone who had ben deadbeated after playing only one turn. he lost 4 points. how does he loose less points hen i played so much better than him, i dont get it. its not fair point loss. i should have the amount of points deducted depending on how i play not at random. that is what i am suggesting, points be deducted on how you play the game. well or unwell not at random. anyone else have this problem? feel free to tell storys
