this is what i'm getting with my 2 msi 280x. I'm new to this coin (new to mining actually)  and i have a couple of questions about this:

1. is the low WU normal? its a different unit from what i'm used to so I have no idea if its still within 90% of the hashrate.
2. how many hero coins do u get with 1 280x per day? sorry i dont trust the pool statistics
3. since mining this coin gives me lower temperature than mining others i was wondering if its consuming less power to? i don't have a killawatt
