The blocks must have been on a soft fork,
"genproclimit" : -1,
"hashespermin" : 8.60285533,
Thats with a 8 core AMD ..so expect blocks to get very slow when the difficulty goes higher.
The PoW is insanely hard , i bet once it reaches 0.00000005 you'll see a drop in block production rate. i'd be shocked if the difficulty ever reaches 0.000001 in this coins entire PoW lifetime.
i get 20.83910475 with my 8 core intel

and for now, it looks like i´m the only miner

so, im off to bed... really tired.... cu
