Impossible. Lou Camilli didn't work with pulsed power technology for Sandia Labs until 1987-1988, and the first iteration of the Pulstar technology (the precursor to the HotShot) didn't come out until 1994, and was only marketed to racers. The first patent for the Pulstar technology wasn't even filed until 1999. HotShots didn't come out until 2001. The first Pulstar plug wasn't released until 2006.
FYI, this is why I bought the plug, given that I'll be experimenting with alternative fuels and lean lambda:

I think if your ignition system is already doing well at lighting the fire, you likely won't show an improvement. For motorcycles, especially waste spark systems that are already on the edge due to increased compression and high RPMs, they apparently do.
I haven't been able to verify any MPG difference with the plug because two tankfuls ago, I changed out my rear gears for 15% taller gears, then one tankful ago I swapped in the Pulstar. But it does idle smooth now, and that can
only be attributed to the Pulstar, given that it was the only change made immediately prior to the bike starting to idle smooth.
