I bet: the vast majority of drivers see enough variation in the fuel economy of their "usual driving cycle"
without even
changing anything that results from that approach would be statistically insignificant.
You'd have to be measuring something that provides a massive change for it to rise above the static.
That said, I hold the testing regimen of a person or magazine hawking a product or junk science to tougher standards than the average Joe trying to figure out if, say, his cardboard air dam (or whatever) is helping his MPG. Meaning: I'm less inclined to jump down Joe's throat if his testing isn't rigorous, though I'll still be respectfully skeptical of claimed results.
