For two weeks each year I go to the IOM TT/ Manx GP. I have watched literally hundreds of riders go off the line with stickers on their new shiny tyres and hit top speed straight away. But if you watch and listen to the on board footage, of which there is many hours on Youtube, they all take it (slightly) easier for the first few corners and miles.
I rate their "real road racing" opinion, higher than your gravel trap/air fence cosseted track racers and tutors.
But, I do also agree with you that the profile of a new tyre makes a bike feel different, and could mistakenly be blamed on the coating.
