So 1024 in the miner and on worker page of the pool guarantees no issues outside of a problem with the pool or the miner. That said, am I correct with the worker setting of 128 for my Prospector200 machine since the next jump up is 256 for 256Gh + ?
Yes, 1024 for a dragon is the recommended setting, and should guarantee proper results while mining without any weird stats popping up. I'm not familiar with the prospector 200, but if it's under 250 GH/s, then 128 is the recommended setting, yes.
However, as far as I'm aware, the only ASIC where the setting *can* cause a problem is the Dragon Miners. Anything else is just a recommendation, it should have no material effects on other hardware.
Good to know, I also have an rPi for fun with 17 BE's and 3 U2's giving 10-12Gh/s... I keep the worker setting for that with a minimum of 2 since the hash can vary based on what I add or remove.
So right now on that we have a worker min of 2, this for speed (10.40/11.58/10.23Gh/s) and what is apparently a working diff of 4 if thats whats after the xx/
