The front end geometry of a tadpole is pretty much the

That reminds me of the joke about what the critical speed was for the
old Morgan three wheelers and the answer was any speed when the back
tire blew out. But I rather doubt YOUR premise about a diamond frame
rider making constant adjustments (except perhaps during hands off
riding). At speed a DF is rather forgiving and you can actually work
against the bike (within reason, like when removing a jacket) for some
distance before things become truly dicey.

OTOH, the Vision was completely stable when I removed my jacket. Of
course, I was stopped and had both feet on the ground before I would
attempt it.
