Hello pool waflfe..

mining for x11 now.

May i ask, is that setting -p d=256 for example set for pool difficulty or network difficulty?  Because when my miner connects to your eu pool, it says connected to eu.wafflepool...  difficulty 0.160 as user xxxxxxxxxxxx  difficulty 193

Then when miner starts it says pool difficulty set to 0.160. network difficulty set to 193.
 So my question is that setting sets pool or network difficulty?

Thanks

edit: it seems like it is for pool difficulty, so may i ask what am i doing wrong that my set difficulty is not recognized ?

sgminer.exe  --kernel x11mod -u xxxx -p d=256 -o stratum+tcp://eu.wafflepool.com:3331 ...

Thanks for help
