Electronic ignition triggering gives you a cleaner spark pulse than
a points ignition. IOW, there's more energy in the electronically
triggered pulse than if you use points. When you make and break a set
of ignition points you get arcing at the contact surfaces. This arcing
messes up the rise and fall time of the ignition pulse. IOW, both the
on and off dwell times vary and there's a measurable amount of energy
lost. That's one reason electronic ignitions took ove; there was less
arcing at the low current draws. If you look at yur automotive
history, you'll see that the points-controlled transistor ignitions got
better gas mileage than points-only ignitions. That means a better spark.
I rest my case,
