Maybe you can explain how it is that when they test Iridium plugs
against stock plugs, the tests always show an increase in HP and not a
decrease that would obviously manifest itself 50% of the time?

Of course, if it did consistently show decreases, mechanics wouldn't
leave them in, nor have any reason to promote them.
I don't see mechanics or advertisers promoting vortec cyclones on
NASCARs.....because they don't work.

Yeah, ah, Iridium spark plugs are only "better" in the sense that
they might last longer: they do not increase an engine's
horsepower.

I already explained that: sampling bias. The "tests" were not
double blinded.

No, instead we see NASCAR hacks promoting Enzyte and U.S. Fidelis "extended
warranties" So much for credibility.
