---Getting to long---
So if you have 4 machines running 100gh, then whether you're multiplying or dividing it's done per 100 / machine and not the combined total of 400 ?
If that's the case, then one would need a worker for each of the 4 machines.
Not completely certain about that one, maybe doc can elaborate on it. I will definitely ask the other guy about it. I have 4 v2 blades and it shows ~40-44 GH/s but I did a little experiment and set my minimum to 4 and checked the proxy about an hour later and it showed a diff of 32 so it was being adjusted automatically, only thing is when my wife started streaming Netflix on the tv and I started loading the network it dropped to 16. So if you want to keep it above a certain number set it to that.
I will say this, slush's proxy with the midstate compiled is faster than bfg miner in proxy mode. Slush's I average 41 GH/s, BFG Miner I averaged 35 GH/s, big difference in my opinion.
