Consider these three scenarios.
Scenario 1: Voters don't rank now, but will rank when they see it's
worth it. Here IRV will eventually crash but BTR-IRV is, well, better.
Scenario 2: Voters rank, contrary to your assumptions (but suggested by
international evidence). Again, BTR-IRV does better.
Scenario 3: Voters don't rank and never will. BTR-IRV is here no worse
Under what scenario does BTR-IRV *lose* against ordinary IRV?

Yes, but to back up that presumption, you have to more or less assume
that America is so special that the claim itself is impossible to disprove.

Plain IRV itself is enough to "improve" upon FPP. This is like saying
that I don't have to run very quickly to outrun a turtle.

That won't help when the correct candidate is center-squeezed out of the
way. The only way to ensure there is no center squeeze is to limit the
number of candidates to two - and then you have plain old runoff.
