I'm a newbie to Blade mining. I've been mining with 28 USB erupters through cgminer but recently decided to upgrade to two blades. I'm confused about configuring the blade. On the page  "192.168.1.254:8000" to configure the blade I'm unclear about the IPs How do I find the IP of my stratum proxy?

Why does my EStimated Reward constantly fluctuate up and down? If my shares are constantly increasing shouldn't me reward? It's like I gain .01 but lose .03 wtf?
