Same player, seperate databases, different results, what do you think?

[ConfusedAgain]

I play on both a laptop and at my desk, a lot of hands on each. My win rate is better on my desktop; more focused rather than watching TV also, etc. Maybe you are more focused at your laptop. I think screen size also helps. Could you possibly be more focused at your laptop or could casual play be more +EV for you. I have over 100k on each.
