Tested some of my hashing power here for a while since Terk said the reject rates had improved...  at max, CleverMining reported slightly under my actual hashrate, and rejects averaged over 20% still (and I am very close to the server...)!

Looking less profitable then wafflepool, and the BTC/day/MH rate published appears to be an utter joke since the site is definitely under reporting my hashrate (tested continuously for about half a day), and then I am losing an extra 20% to rejects.  Looks like nearly a 35% inflation of BTC/day/MH compared to wafflepool which has been a consistent a slight under estimate.

All my hashing power is back on wafflepool for now.  Will try again if reject rates actually improve.
