grs.suprnova.cc Hash Discrepancy

[TRexMcStubyArms]

Hey guys,

I just started mining Groestlcoin at Supernova and I'm seeing a pretty huge (10-60%) discrepancy between what supernova is reporting as my hash rate (40 MH/s to 90 MH/S) versus the consistent 101.9 MH/s that CCminer is showing on all of my shares.  I've read a few posts saying they're a scam and a few posts saying they're trustworthy.  I'm not so worried about the 10% difference but when I'm mostly seeing the 40 MH/s, well that's like operating only 1 GPU.  Not cool 

Thoughts anyone?
