why the stratum difficulty goes up and down. not stable anymore in x17 algo. what is the best diddiculty setting for every algo?
Because the nature how pool is calculating your hashrate, it is not very accurate and you can see it changing about 20-25%, while your rig pushes stable hashrate.
That is why the stratum diff is changing. But in a long run it really does not matter. Imho, do not bother with it
