Proof-of-stake Difficulty

Is there a calculation that we can use to understand what the current PoS difficulty represents? The last couple of blocks solved have been right around 8.23, so can this number be extrapolated to approximate the number of people attempting to mint across the Peercoin network, in the same way that PoW difficulty equates to global network hashing power?


Bump. Also very keen to know whether there is a relation between difficulty and the coinage on-line
