scoring system

Could someone please explain how the scoring system works? It seems that the longer you stay in the game the more points gets deducted if you don't win. This is counterintuitive to me. If one plays poorly at the beginning of the game I would think more points would be deducted when s/he is eliminated early than if someone plays well and is eleminated near the end of the game.
