Point taken. You are aboslutely right, and I should have added a
disclaimer regarding platinums. I can only plead to having centered on
"stock" ignitions, I assumed (there's that word again!) standard type
plugs. What makes it worse is I too run Bosch Plats at about .050" gap
with a standard ignition system!!

True, but that imprecission (due to the timing chain/gear wear and flex)
is present no matter which system you utilize. Discounting any wear
outside the dizzy, the electronic system will always be more precise.
Now, you're probably wondering why I don"t have an electronic system on
my car.
Simple inertia. For what I do with my car, the point type works very
well, and every time I think I have enough money to replace a perfectly
good distributor and coil, something else with a higher priority raises
it's head.
One of these days!!
