Let me start by stating the obvious - zwift has no idea how drafting works IRL. But it is forced onto their users so there we have it.
Lately, I have noticed that my avatar does not know if it should be drafting or not. I’ll be sitting in the MIDDLE of a huge peleton (50+) and the avatar would pop up and down randomly. My understanding of the crap drafting implementation is that if the avatar sits up you are drafting and if it is ducking down you are not. So I’m wondering, am I not in the draft when my avatar ducks down in the middle of this huge peleton? I am not on the side but in the middle when this happens. Probably not a bug but a feature of the useless drafting ‘logic’.
