I am seeing improvements in the last few rides on the old and new course. Drafting much more realistic now. No longer so hard to stay in the draft during non-sprinting efforts , and the constant slingshot effect is much reduced!
I have noticed this also but I find the CdA to be pretty tough on larger guys like myself. I really struggle to pull away or even catch up on downhills now even when putting out more watts than the others. I think they have went a bit too far the other way. This was mainly noticed on Jarvis during March. Not rode beside many yet on Watopia so not sure if it is the same here.
