I still am of the opinion that a stochastic variation superimposed on a slowly varying 'PE' will not benefit from any pec training as far as autoguiding is concerned. It is even more apparent when no two cycles are the same. If the mount has very high pe variation then it will inevitably have backlash and poor 'jumpy' gears.
I have two mounts with belt drives and they have no discernible backlash and are very smooth. There are no gears. In fact if I set the aggressiveness to high I can get lovely 2 or 5 second of arc oscillations with constant period as the system starts off by chasing the seeing and then keeps self overcorrecting.
If I set any backlash value the same thing happens.
It basically is a matter of balance to get all the variables correct. I think it is foolish to correct for something that is itself unpredictable unless you have a lookup table for a 360 deg cycle. Then you have to know where you started!
Or am I missing something?
