Please help me understand this:
Just started experimenting with samr7/oclvanityminer and have dedicated a 5850 to the task. According to the calculator, I'll earn a little over .11BTC per day with this card doing normal (non-vanity) mining.
It's currently hashing around 20.20 Mkey/s and working on this problem:
"1vanity" Reward: 0.079600 Value: 0.000323 BTC/MkeyHr.
So that's 0.000323 * 20.20 * 24 = 0.1565904 BTC, right? So I should be earning more than I would if I mined straight? But then they take 20 percent out first or does that figure already have the 20 percent taken out?
It also says 50% in 8.0h, I take that to mean there's a 50 percent chance it will find the solution in 8 hours. So approximately 100% (statistically) in 16 hours, that means the reward (0.796) for 16 hours average work? So 24/16 * 0.0796 BTC = 0.1194 BTC which is not close to 0.1565904 BTC. Where is my math failing?
Does my Mkey/s look reasonable for that card?
I was interested in this too and realized there was very little out there to help people figure this out, so I wrote some scripts to do the calculations for me:
http://fizzisist.com/mining-valueAs for the statistical stuff, the BTC/Mkey stuff is the number you should be using. This is the expected earnings on average with the current pool of work. It doesn't matter how long you mine for (although as you mine for longer time, your earnings will approach that of the average, yet can be subject to huge statistical variance over short time periods). Bitcoin solo mining has the same problem, so pools were invented. Unfortunately, vanity pool isn't a pool in the same sense, so you still have quite a bit of variance, although MUCH less than solo mining bitcoins.
