Secondary Ignition Trace: Measurement Artifact? Or Evidence?

Hi Folks, first post. Looking for a little advice. Go easy on me please :) Pertinent details: twin-distributor V8, old-school: two coils, one feeding each distributor. Chasing a misfire. The only evidence I've been able to find is displayed in the traces below. (These are all from one of the coil (K...
