Not sure I understand the underlined part ?
I think I possibly misunderstood your question and was remarking on the entire ignition event. But possibly where the clamp is in relation to fault will yield different results.
For example the rotor notch on the coil lead but not the plug lead. Although wasted spark is different again.
Nice animations though Rob.
Wish I had read your posts earlier. But here's a few images from a wasted spark system that I had yesterday that had very high resistance in the secondary coil.
At idle it appears very hashy. Underload it becomes very chaotic - each event different from the next. I couldn't say weather the partially fowled plugs were contributing to this.
Personally I find ignition hard at the best of times.
