Probably a bit true. Makes sense for Sega di Ala too. Yates was reverse yoyoing a lot there.I think steep gradients kinda help him in a way. Once it's steep enough/slow enough that drafting doesn't really matter his way of pacing himself becomes a lot more efficient that following every acceleration and buring yourself out that way. He did ride a pretty good Giau ascent (anothr steep climb) last year after being in the breakaway.
Still I'm not super high on Almeida as a pure W/kg climber. His 3rd week of last year gets mentioned a lot but on the hardest Spluga he also dropped somewhat handily. And what's coming can be pretty pure W/kg.
