Anecdotal but I wonder where CVTs could be today if it weren't for the F1 ban on them after Williams Racing made tests runs that indicated a 1-3 second per lap advantage over fixed gear configurations back in 1993-1994 (?).? 7 minute video but fascinating telling of the story. And the sound. I think of this every time I floor my Honda CRV (haha).
