1mh GPU power - it is about 450W - 10,8 KW/day - in Russia it costs about 0,00283 btc/day (0,113$/KW)
so 0,00426 + 0,00283 = 0,00709 btc
...
So profit 0.006 is good, 0.007 - very good, 0.008 - excelent.
I doubt that scrypt.cc can reach this profit every day...
I think that your error is in power cost calculation. I think that it is possible that scrypt.cc pays much less then 0.003btc/day/mhS. It is not in Russia and it can buy power for special price for datacenters.)
