Thanks!
So in my scenarios, I should be using Pool 1 since it has a much higher "U"? Any idea why it's so much higher?
The two different pools are using variable difficulty and they have different targets for that difficulty. Your WU:, aka Worker Utility, or diff 1 shares, is the same and the pools will convert your shares back to diff 1 to pay on. So both pools will pay on about the same number of shares.
