Time under tension doesn't matter if you're not accounting for intensity. Also you don't seem to make a distinction between the eccentric or the concentric part of the lift. Time under tension at the bottom is significantly more hypertrophic than time under tension at the top. Within the last year there was a fairly big study suggesting that how slow you go down doesn't matter as long as you're between 1-3s. Most people can implement this without the need of some wearable tech. Your analysis of why basketball players have big delts is flawed. You can do a thousand reps of lateral flys by just flapping your arms but that won't make your delts any bigger. At a certain point you'll have to add more weight. Why is it that basketball players like Larry Bird don't have massive delts? Probably wasn't because he wasn't shooting the ball as much as players today.
This dude's whole claims are all flawed lol. This is all broscience which has been debunked over the last few decades. Everything you have mentioned in your comment in contrast is all true.
its just small optimizations that dont matter for most people. Might hold value for professional bodybuilders, but anyone just looking to stay in shape, build strength and look decent can do just fine without.

Big facts brother this giy is flawed, i might add that the latest litreture of ecentric control suggest anything between 2-8 sec not 1-3.
Runners don’t have big calves even after decades (sadly)
So should spam shoulders everyday? Ofc i wont be hitting till failure unless i recovered
