"Of course the firing event happens in the same place as far as the reluctor and pickup are concerned. The rotor will be ahead of where it was with no advance. It does not have to be spot on under the terminal to have the transfer of the spark."

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO! the rotor will not be advanced compared to the pickup, reluctor, or cap. It will be in the same position at all engine speeds.
The only change in rotor phase will happen with vacuum advance or external timing controls.
