I have configured a yiimp pool for some yescryptR16(Yenten, Cryply, Elicoin) and yescryptR32(Wavi) coins.
The problem is that if I configure stratum difficulty to be under 1 I got 100% rejected shares, some of them invalid shares, some of them Low difficulty shares.
I I use 1 or more, it works fine, but most cpus take a lot of time to accept a share.

I have seen some yiimp pools with difficulty to 0.001 or 0.1.... any idea on what i have to do?

Thanks,
Witxo
