I say Time + Skill are completely linked in this game. The more time you have to play Elo, the more experience you gain. The more experience you gain, the more likely you are to get higher Elo Scores, no?
It's easier to get the higher scores as the week progresses, that's also something worth pointing out. If you can get the 1300's on the Thurday's or Friday's you can put in a solid attempt for 1400.
