Bill, you're right, of course, and I should not try to define exactly
what sizes are common practice for the purpose of this
experiment/challenge. This is more about the method of flying than
any particular rubber size or prop size. My intention is to
advertise tradition, for sake newcomers trying the learn something,
and my own sanity, that the following simply isn't true, if high
times are the goal.

It's not that simple, and the lower the ceiling, the less true it
is. But as long as Gary Hinze follows his own advice in his above
teaching, I will be happy with the experiment.

I think one may never know how "meaningful" an experiment is or is
not, until it's accomplished. Afterward, we can pick it apart, and
maybe improve upon what is being tested. But I agree, one episode of
flying won't settle this, especially if one side merely "adjusts
explanation" to the other. I mentioned before that theories are
neither proven not disproven, but are rather supported or not
supported. If I can show to a few interested newcomers that our
bread sticks do not support the baloney in question, then it will be
a good experiment. In other words, the usefulness of our body of 60
years of common practice concerning "how to do this indoor thing"
will trump GH's seemingly mathematically imposed beliefs every time.
At least if the stopwatch is the judge, and it's all done honestly.
That's not say I don't believe in Mark Drela's appled math!

Just as a concerned citizen this time.
