I'm having a lot of trouble guiding my Paramount MyT with the internal guider.

My results (rms, eccentricity) are substantially worse than unguided, so I suspect that I'm overcorrecting. My polar alignment is dead-on, and I can do 10-minute unguided exposures, but I hope to be able to tighten up the stars a bit.

I realize that Hy has recently implemented a bunch of wonderful new features, and I've been very successful guiding my iOptron CEM40. But I can't find documentation on some of the new parameters, which I want to adjust to make the guiding less aggressive. I'm especially interested in better understanding the following parameters:

Prediction Gain
Control Gain
Proportional Gain
Integral Gain

Are some of these in pixels and others in percentages (or fractions)? Does anybody have any idea of how far to back off these numbers if I just want a light touch of guide pulses every ten seconds or so to eliminate drift?

Screenshots attached.

Thank you!
