Currently it sits at d=7.23843342. This jives well with the block reward I just received (r=19.07).



(999 / d^2) = r <=> d = sqrt(999/r)



So, with a reward of 19.07 we have d=7.23781.



In the time it took me to write this, the difficulty changed to d=7.24123460 in about 15 minutes. So, if my math was right the difficulty increased by almost 0.04% in 15 min or almost 0.003% per block. Using both of the blocks I found gives around 0.002% difficulty increase per block. This is all assuming a one minute block time, so take this all with a grain of salt.



According to Bitcoin Magazine, a doubling of computer power would cause a 0.02% increase in the difficulty of the next block. I'm off to bed!



source: Is there a way to check past difficulty levels? Or did anyone take note of what it has been? I'm going to attempt to keep a log over the next few days to see if we can get an idea of where the difficulty is going (and therefore what the reward/inflation rate will be). Also this should be useful in determining the compute power of the network.Currently it sits at d=7.23843342.

Absolutely nothing on Core2 6660 2.4 with around 4-12 PPS (7khash/sec scrypt)



Gonna try the luck of an old Toshiba Centrino Duo laptop... who knows, it only gets about 4khash/sec with scrypt)



Is there any info on mining with more than one machine through a single wallet? I am looking... Found 2 primes on Asus i7-3630 2.4 Laptop (Gets about 30khash/sec scrypt mining)Absolutely nothing on Core2 6660 2.4 with around 4-12 PPS (7khash/sec scrypt)Gonna try the luck of an old Toshiba Centrino Duo laptop... who knows, it only gets about 4khash/sec with scrypt)Is there any info on mining with more than one machine through a single wallet?

Specs: I5-3570k at first with just 3 threads, now 4 for the past ten hours or so. Running a VM in the background though, and the CPU utilization is around 99%. Windows 8 64 bit. Here is another screenshot showing the unpredictableness of this.Specs: I5-3570k at first with just 3 threads, now 4 for the past ten hours or so.

The fit line is y = -0.005740965 * x + 45.7769270



The mean is much lower than the fit line, at 36.02s.

Thanks for the chart rethaw

It would be interesting to sample the outlying block intervals to see if there are characteristics of the preceding block's hash that made it harder/easier to match with a prime chain. I know this isn't an influencing factor for SHA256/scrypt block chains, but it could be for prime?
