I'm a fan of your endeavors, but you're ignorant of differing cycling goals. There's a chasm between what you do and what I do.
Oh heck J, a highly visible subset of cyclists dress and ride in those otherwise entirely silly outfits, buttered crotch, sunblock and all because it works for a narrow application.
As a group, these people riding in close packs on public highways, also infuriate lots of folks.
With respect to those snap-in pedals I have read the same articles and seen the same YouTubes as everyone else pertaining to their advantage or lack thereof (IIRC the upstroke’s contribution is negligible). I will acknowledge that to have your feet come off the pedals in competition can result in cut-up calves pretty quick (a big reason why you guys also shave your legs, cleaner cuts).
When you do go on tour, ditch all that silly stuff, there’s other ways.
