Mined now for few days and seems that phoenix is little faster than claymore.
After adding -mi settings, started mining better. -gt still auto tune. started mining prezzed Z and -gt was calculated.
Notised that after coin network difficult changes about 10TH (up or down), then was need to auto tune -gt setting again, was mining better.
So there is suggestion to phoenix , can you add setting that monitor coin network difficult and if changes in difficult are big then phoenix calculates new -gt settings.
Exsample: ETC dif 197TH calculated first, dificult rised to 206TH need to calculate again -gt settings. And this up and down goes every day.
This few minutes autotune is worth.
