wow, nice strategy. I'm on slush with quite constant 60 GH/s with 3 BF-H-cards. I get around 0.5 BTC daily at the moment. I see there is space for improvement, thank you 
Are you mining on : mining.bitcoin.cz ?
Most I get is 0.3BTC / day with 60 GH.
I do, I had the 0.3 / day as well, before I found a little trick that made my hashing constant (before, the rate fell to trash every night). In the common sense that obviously roams around in the BTC world, I could pass this knowledge to you, in exchange for a small contribution of, lets say, 100 BTC?
or
just give it out (I use /60 not /10):
Someone may find this useful... If your pool reports your hashrate dropping regularly DESPITE bitfury admin showing steady noncerate:
1) ssh into your pi
2) run command: crontab -e
3) add this line at the end of file:
It will restart your stratum proxy every 10 minutes from now on. If you want to cancel it, just run the command again and delete the line.
