Dennis,
I have not had a random misfire in steady state cruise that I ever noticed. This has been the case with the stock Mazda coils and the D585 coils. I’m usually running about 19-20” MAP.

On run-up I get about 50 rpm change from both to leading or trailing. I normally do the check at about 3200 rpm.
Now that you mention it, I would guess that the occasional misfire is "probably" a total misfire of one rotor face. Don't really know though!
Do you ever have a similar event?
