GCN is rather absurd, they will put someone stronger on the TT bike and make a contrived video. They are just another arm of Big Gravel trying to n+1 you and the perverse thing is that they always have been. Pros drafting will be about 30% more efficient than solo, Id be very surprised if a TT bike increased efficiency by 30%. Bents are banned for a reason, besides they are afraid of hills, but yes they are killer on flats. I kind of want one.... there is some stigma for some reason though
