I give up: What's a PIO?

Pilot Induced Oscillation. It's usually something that happens during
the landing flare, but can happen on a short-coupled aircraft in any
phase of flight. I wasn't aware that a Bonanza was in that category,
but apparently it is.

It's more of a short coupled pilot that airplane.:-))
A lot of pilots get used to responses of a Cherokee or 172 and for
some reason lean to rely on the VSI to stay level. That doesn't work
in the Bo which is much quicker in response. Where as if they see the
VSI showing a climb in the Cherokee and correct the Bo is quick enough
they can end up 180 degrees out of phase which makes for an
interesting ride. I usually start out by saying, "Remember, the VSI
is a *trend* instrument".

Isn't it bad for your aircraft to put it through 2 G stresses?

The Deb is utility category when loaded properly.
2Gs. Loop entry in the G-III is or can be around 5.:-)) Or a little
more if you want to do two with one on top of the other. Of course
entry speed is a bit higher at 350 MPH.

BTW one of the things I enjoyed out of 16R was seeing an old Ford Tri
motor (think it was a Ford) doing a "low altitude" loop
