Dear zawawa, I have some test result for u..
You can see how different is the total shares in 10 minutes..(everything is same, intensity, algo, pool, clocks, settings etc..)..

Sorry for watermark , I will say , "i was there" when your program reaches millions
Hmm... Let me see...
Edit: I checked my rigs, but I didn't see any discrepancies between the locally reported hashrate and the hashrate reported by the pool. Strange, strange... Could you check the hashrate reported by the pool with the new version?
