Yep. The only big takeaway I've had about Guezy, from various things posted on here, is that the person feels he doesn't need to sleep as much as Walker claims and sets out to prove every little tidbit wrong that Walker ever said. And perform experiments on himself (there was one where he intentionally sleep-deprived himself then tested his reaction time on a video game, if I recall correctly) to say "Look, we don't need to sleep that much!" Honestly, it seems he more has an issue with sleep and is looking to optimise for time awake, thus he basically hates Walker telling us we probably need more sleep.
I've also found a lot of these points to be quite finnicky too, as [1] discusses
