Getting allot of :
Network diff set to 5 and Stratum pool 0 detected new block and betweend that accepted codes..
is this normal or must there be only accepted?
Along with lower hash rate, your GPU's will require a lower pool difficulty to submit shares at a similar rate. The vardiff on pool should adjust down to your WU rate and you should submit at normal rate shortly.
I've given links before, but there's only one chart I can find for the nfactor retargetting. the dates on this will be off, of course, as it's a different coin. Maybe bumface can give the proper dates. I assume we just went from N9-N10....but not sure.
