Ok, now that is an explanation I can understand #loveit!

Thank you for taking the time to explain it to me like that makes complete sense now. Even though I have one wallet and am mining to one address it is still making micro transaction (pennies into my wallet) so instead of just creating one lump some it has to pull all those transactions together to send out the amount I want to send. But once I send that one big amount it is now treated like a lump some rather than a bunch of smaller sums.
