I would not. For one thing, it has everything to do with a person's style of pedaling. If the 3000 subjective comparisons were all done seated and only pushing down on the pedals, then of course there won't be much difference between clipless and platforms. He probably wasn't trying to compare clipless with platform; if the conclusion drawn is more of an afterthought, the subjective data is really meaningless. Whereas the data points of someone who is making a true, purposeful comparison, seated, climbing, using circular pedal strokes under more controlled circumstances would be far more meaningful.
