For what it is worth, I often float over the top of a loop at 60 knots,
which is about 10 knots above stall speed. At that point, the elevator is
more or less neutral, and the airplane is performing a -2g arc. One of the
g's comes from aerodynamic lift and the other comes from gravity...
That's only a .5 G different arc than the beginning of the loop, which was
a 2.5 g arc: 3.5 aerodynamic g's in the "up" direction minus 1 g from
gravity...

With respect, I am a little confused as to what you are saying here.

Please clarify what you mean by a -2g arc?

IIRC, I normally see 0g to -.5g when 'floating' over the top of a loop and
with this low g loading the aircraft will have a very much reduced stall
speed.

I see no reason to add (or subtract) extra gravity to the g meter reading
when calculating load or estimating resulting stall speed.

I do not mean to be argumentative here, but I seem to be missing something.
Are you talking about the resultant radius of the arc?

Happy landings,
