12 minutes per hour is 20% a day that goes for the dev.
LOL, just use awesomeMiner which is free to use. It has all the bells and whistles + many more features.
You mean all the bells and whistles that are locked behind a pay upgrade?
also it's not 12 minutes every hour. It's 12 minutes per 12 hours of use.
-EDIT-Huh my miner just stopped. Also it looks like zpool.ca is down. I assume that's the reason.
