“Come now to Monaco and to Baku, what that sadly uncovered is a second difficulty that was being masked by the primary. I’m assured we’ve made a step ahead when it comes to porpoising, however we very clearly have bouncing, and to the surface it appears virtually equivalent, however there’s a delicate distinction between the 2.”
