Pack dynamics 2.0 was even worse, 3.0 we using now is better but still has a lot of issues for sure. Especially on downhills in large packs at speed.
6.5 pulls would have taken us back across to front group for sure but every single person in the back of the split had someone in the front of the split. So nobody was going to ride and close that haha.
Took the liberty of re-watching the race from where it split. From what I can see it looked like a big push for the points at the top of the kom , lots of heavy sprinting going on. This seems to have caused a gap to those that weren't going for the points and it immediately went into the downhill. Sprinters group just naturally had a gap and it never closed from what I can make out
