You'll kindly notice that it was YOUR analysis that required an
infinitely large propeller. My analysis works just fine as written
and involved no such thing. It's a fact.

Had I picked exactly wind speed to analyize (as YOU did), I would have
picked a different (but equally as accurate) method. Not all things
are perfect for illustrating all situations.

I might add here that you have yet to produce an *accurate* analysis,
let alone a persuasive one, so you might want to go a bit easy on the
high horse.
