Isn't it about 150TH, not ~5-7?
Nope. Labrat said that 55% of the BitFury gear is up and running already. The current total hashrate is only 17TH, half of which is BFL gear. So that must mean that about 5-7TH of Bitfury gear is left to install.
I think Labrat bought 100 Monarchs.
That hashrate hasn't budged in months so I'm fairly confident it doesn't included the BitFury gear. Effectively there should be around 25TH online but 17-18 of it is at cex.io.
