This makes alot of sense now...
This height thing is extremely disappointing lol
It takes alot more than knowing height to determine CdA
Zwift apparently knows my flexibility, bike positioning and whether I climb in saddle or off saddle (yes that matters IRL)
Gimme some damn crosswinds or some mechanics that help us lose these tiny guys on the flat then, drafting is so OP on the flat.
It appears everything is skewed to benefiting small man performance.
I agree that height is a crude measure but good to Zwift for seeking to improve accuracy. As for the other comments in this post i think it's the opposite. Zwift algorithms are tipped to strongly in favour of heavier higher watt producers rather than w/kg. Even on a climb these big riders don't seem to get dropped like you would expect in real life.
I rarely see any good riders on the real roads who are 90+ KG but on Zwift there's a few.
This is so true with my own experience. I need to ride the balls out of my pants just to get a few seconds, but then shortly after the downhill starts I am overtaken and droppend behind. Just insane!
Furthermore, I assume there is something really wrong in Zwift if it comes to calculating speed in groups. It seems that groups just go faster and faster due to the draft effect, yet the produced wattage of the front riders is far below the needed speed. It is completely different than IRL in two ways: (1) a group will never go faster than the wattage produced by the front rider (2) while in draft your resistance will drop dramatically while in Zwift it stays the same.
Especially (2) will cause the group going faster and faster with riders overtaken eachother.
Also all the mentioned tests don't really matter since it is in a static approach, while a race is quite dynamic. And all is based on fictive values rather than real values. A shorter rider will produce in general far less watts than a longer rider, although there will be always exceptions in real good riders. You can not use an expectional rider to prove something for in general.
