am just not understanding how much it will contribute since you are effectively referencing the voltage in question between a tap point and output.
Just draw out your own copy of the drawing from the above post and don't place the battery polarity symbols on the drawing just yet. Then place the + and - on the battery connections either way then reverse them. You will then see that the plug is still across the entire coil (primary and secondary) no matter how the battery is connected. Don't get hung up on the word ground. In this case "ground" really doesn't mean anything. The ckt will work the same no matter what the battery polarity is.
I accept the explnation regarding why it is better for the spark to travel from the center electroide to the outer case of the plug.
