I'll show you Ken G.'s write up when we get together to work on the NJTA
website.
Also, <OPINION HERE> I figure the platinum would work like a catalyst and
kick off the burn process at a lower temperature (like all good catalysts)
and result in a longer burn duration. Longer duration, more power generated
<REMEMBER, OPINION HERE>

If you mean the four prong Bosch platinum plugs, I'm running them in my Saab
and Chevy. I feel they start faster when cold and the Saab digital MPG
meter, good for the last 1,000 miles is definitely up approx 10%. BUT there
are definitely other factor at work there too. My seat of the pants says
it's better, but I may just be justifying the higher cost to myself :-)
Without a dyno, there is no way to tell.
Later,
Jack
