I await your explanation of Vr and what it depends upon

I've never flown an airplane with a published Vr. Since you're the one
making claims about how it's determined, how about YOU explain Vr and what
it depends on.

As far as Vy and Vx not varying with engine power (your claim regarding "one
cylinder completely flat"), you may not have noticed the difference in the
cockpit, but that doesn't mean they didn't change.
