I am not racing so don't really care a whole lot about it, but it's indeed frustrating to lose the draft benefits on Zwift (for whatever reason), get gapped, dial it up to 400W to get back to the group only to be dropped by the group in 2 minutes because I can't maintain the (previously sustainable) effort required.
