I'm running 560 Gh/s and only getting .04 BTC / day. Man, I miss a couple months ago. And people said I could run this miner for several more months. I doubt that.
You got somethin wrong there, I'm avg 0.03 a day an I got just north of 180Gh/s.
You should be seeing 0.08/0.09 a day with your hash.
Edit: FWIW, you can run your miner aas long as it at least pays for itself in electricity.
All I need to do is make $60 a month with the Avalon I have to make it worth while to mine.
