Just set up some machines on Friday. I'm at about 3.3 Ghash. Since then I've been trying to get a handle on how many btc/day I should be making. According to this site: http://www.alloscomp.com/bitcoin/calculator.php
I should be making about 3.7 btc/day. So I was watching my btc/day go up (I only had 1 computer running prior to Friday). The ratio got pretty close to 3.7 but has been declining steadily now. I'm below 3.
Mining primarily on BTC guild this week. I checked the block stats and it's not an error in the site's btc/day calculation. So I'm a bit puzzled.
Why are my btc/day going down? From what I know, the difficulty level hasn't changed much. The site still shows 877227 which is in line with what I've seen elsewhere.
At this rate, I'll be mining less than 1 btc/day in a few weeks. That makes no sense to me.
Comments / input appreciated.
