Transfer/Transition slot adjustment

Cuda416 said

Just addressing the total advance based on the slots quickly. I had it out the other day and measured them. My caliper told me 0.470, just shy of the measurement for 15, or as I understand it, 30 total so unless I have that wrong, it's what I've got to go by until I can take an actual measurement with a degree wheel. Oddly there are no marks on it whatsoever. I was surprised by that.,

You got it right.
Leme take a quick look at my spreadsheet notes
edit:
yes that agrees with the measurements I've made as well the various articles.

If you've seen the video @yellow rose posted, it shows how the time used for electronic switching steals a degree or so every 1000 rpm. We really only see this after the weights hit the top of the slot. I only mention it as one of several reasons that the stamped number is not absolute.
