I averaged about 4-7mhash at CoinKing yesterday to check them out. Payout was 0.004btc. Clevermining Payout was 0.014btc at 3-6mhash throughout the day... Doesn't seem right...I guess it's not a very long test to be fair...
In my opinion, with the 'mine most profitable coins' feature you don't need to invest days to see how well a pool works. If the result is much worse than just mining dogecoin or litecoin by itself something is not right. You just confirmed my suspicion about coinking...
i rest my case.
