Waldo,
Im sure (from many experiences) that when #3 is hashing @ 50% this means is drawning not significantly more than ~50% of power from the wall.
You can verify this with your kill-a-watt, please.
P.S.
And I think at such expensive power you have its right time for selling Terraminer on ebay
8-9 btc maybe per item is definitely better than todays nothing from mining
(no chances for mining these 8-9 btc already

)
I agree, if we sell this miner and the one we will be recieving it would definitely be in the best interest of the share holders.
Quick math:
If the 8-9 coin evaluation is correct then 2 miners should be 16 coins giving each share 0.2 coins.
And there is no way we would get that mining.
"0.83BTC earned and 0.7BTC in fees?"
We are near from switching off Terraminers, the same as KNC Jupiter last week.
And not working equipment is not earning money, but still losing its value... - because there are little chances that bitcoin difficulty will drop
So we should a little hurry up with voting for selling or not.
Buyers with normal or low power costs (our are not normal, unfortunately) - will still profit from our Terraminers, when we are not able already.
