It is my understanding that stall speeds are measured at altitude (for
the
purposes of characterizing the plane), so in ground effect it will be a
bit
lower.

Also, you'll probably find that the stall speeds at 20 degrees flaps and
40
degrees flaps are very close, if different at all.

Cessna varied its 172 models over the years. Some had a max flaps of
40,
some 30. I think they went to the 30 and a larger engine to prevent
some of
the go-around accidents they'd been having. With the 40-degree
flaps--which
are something like a brick wall attacked to the back of the wings--the
airplane wouldn't climb at max gross weight. If a pilot attempted a
go-around and forgot to reduce the flap setting (or if there was an
electrical failure), there could be trouble.

With max flaps 30 and a slightly beefier engine, it would climb even if
the
pilot forgot to adjust the flaps.

It has been a while since I've flown, but go around procedure is (I
think,
from memory) full power, carb heat off, then immediate reduction to
flaps
20. Flaps 10 and flaps 0 come as the airspeed builds.

A 172 with the 40-degree flaps is impressive. If you go to idle, it
will
have a really steep glideslope. But from a safety point of view, there
may
have been issues. I think the modern ones have a max flap setting of
30.

All this is from memory. Could be wrong.
