If anything Remco seems to be more aerobic and Pog relies on his anaerobic ability, because what keeps happening is that Pog does an attack which opens a gap and then settles into the same pace as Remco who is chasing behind.
I really don't buy that Pog intentionally maintains a certain margin of victory because I think he'd crush Remco by more if he could, to deal a mental blow (see lombardia 24).
yeah, there is nothing to suggest that either rely on one performance attribute over the other. To be as good as they are you need to be superior at both. IMO a GT winner has to be able to ride on that edge of aerobic and anaerobic
comfortably for 5 hours. Pogacar, Roglic, Vindegaard all have been capable examples of relatively relaxed ability. Problem for them and Remco; Pogacar is cruising while they're working. He's a better bike handler, tactician and emotionally stable rider than the rest. He doesn't seem to burn calories being tense or having to constantly recover position.
That's also why he may have no need to pile on minutes to a margin for "a mental blow." All of his competition has had their mind blown several times so that's not even a thing. It can't go on forever as he will be beaten.
