We will see.

Your PEC Curve looks nothing like mine. Mine is much more gentle up and down with only a little bit above and a little bit below the midline on both my PMX and PME. As I recall there are different curve fitting algorithims you can use.
The first time I did PEC curves they looked like that and did not improve tracking on my PMX. I redid them on a night of good seeing and after I had improved PA and did a 20 minute run.
Was this done with Pempro or Sky X?
But the bottom line is do they work and if you are getting round stars in 10-15 minute exposures then you have arrived and I would stop fiddling with it.
