the miner is too complicated to set, we have no course of action you even do not know which setting to put
The next version will have --dagintensity setting so you can push the memclocks even further. We need to find the optimal defaults, in the meantime you have to experiment a bit to get the best hashrates.

Are not the optimal pools for this miner. It's not only about stales, but how frequent jobs are sent out and how much work that needs to be thrown away.
