I've noticed a discrepancy among the payouts between trademybit and yaamp. Trademybit always seems to one-up yaamp by a percent. But when I look at time mined vs payout in miner control, it seems like I put in more time and less payout than yaamp. Is this because of auto-exchange or are the numbers getting jacked around when miner control is calculating profits. I remember reading something on trademybit that the exchange value is only calculated at the time of the exchange which is probably later than the mining for alt coin occurred. This seems a little sketchy.
