i've been looking at my mining data and continue to be very impressed with CP. blood i must thank you for doing such a great job. with roughly a month of data to look at, 1 Ghash/s is averaging .75 BTC/day. the last 5 days alone 1 Ghash/s has been averaging almost .9 BTC/day. anyone else with some comparison numbers? it would be awesome if i was the low to mid end of the spectrum.

I do not know how to do the calculations to get this information, but if you would like I can send you the info and you can calculate it yourself and compare. Just let me know the stuff you need to do the calculations...

all i did was take my average BTC/day for the 1 month period and divided by my hashrate(in Ghash/s)

so if i was mining 5 BTC/day at 7 Ghash/s: 5/7 = .714 BTC/day/Ghash/s, almost as good as my average

. it's a good stat to use when calculating how long a card will take to pay itself off. using that example, a new 5970 from newegg, with price tag of $500 and hash rate of 800 Mhash/s, would get about .5712 BTC/day. assuming current price(1BTC=$8.3) and difficulty remain the same, it would take about 60 BTC, or 105 days to pay off. this is not including electricity costs. using a common mining calculator, such as http://www.alloscomp.com/bitcoin/calculator.php or http://98.200.247.249:81/btc_calc.php, shows it would take about 133 days to pay off if you didn't pool hop. CP is giving me more than a whole months advantage over those poor saps who think pool hopping is unfair, or more than 2 months if i used my 5 day average (which will most likely drop) but is still crazy! now if only i had a 20Ghash farm...

please correct me if any of the math looks wrong

het scatterbrain, you haven't taken difficulty changes into account. If you plot the coins you get in your bitcoin client against days, you'll see a slight curve. You can do one of two things:

Calculate the expected payment per share for each difficulty (50/difficulty), add up the total shares for the period and multiply, and you'll get what you would have gotten at a fee-free pps pool
Only average your results per difficulty period

Hope this helps.
