Pete, what are the numbers on that?

Having accidently scraped the tail on the runway without stalling the
airplane, I have emperical evidence of that fact. Keep in mind also that
the stalling AOA while in ground effect is not the same as that at altitude.

What aircraft type? Sure, if you fly along low with sufficient airspeed
and then yank back on the yoke, I'm not surprised that you could get a
tail strike. However, if you fly inches above the runway and hold the
plane off as the airspeed decays, you can get the yoke all the way back
and the stall horn on just a second before touchdown. I've done it many
times and this is the way my instructor taught me to make virtually
every landing, even crosswind landings in light winds.

If the stall horn is on only a second before touchdown, you have not stalled
the airplane. The stall horn sounds well before you reach the stalling
angle of attack.

True, but only a few knots above in the Cessna's I've flown 150 - 182.
If you keep smoothly pulling back the yoke, the airspeed will bleed into
stall territory very shortly after you get a full stall horn.

Per certification rules, the stall warning must occur AT LEAST 5 knots prior
to stall. In my experience, it commonly occurs with an even greater margin.

No, it won't. The airplane will settle onto the runway before you stall.
You have to move the yoke pretty sharply to keep lift equal to weight at
that airspeed.

I think 5 is considered "a few" by most, even hair-splitters such as
yourself.

Yes, it does require that you accelerate the rearward movement of the
yoke as the plane begins to settle in order to hit the stop at or slight
before the tires touch.

Again, I guess it depends on how you define stall. To me, a stall has
occurred when I can't maintain altitude with the elevator full-up. That
is the condition in which I attempt to land in normal conditions (light
crosswind and lack of significant wind gusts). I've never flown a
Cessna with an AOA indicator so I can't say if I've achieved the
critical angle of attack prior to touchdown, but these have been called
"full stall landings" since before I was born so that is good enough for me.

Each person has their own definition. If you want to split hairs, you need
to use a more precise term. To me, "a few" is generally three, while I'd
use "several" for five or more.

In any case, the real question is how much before you stall will the horn go
off. It goes off much longer than a second before you stall the wing.

[...] but these have been called "full stall landings" since before I was

As long as you understand that you are not actually stalling the airplane,
that's fine. Use whatever inaccurate terminology you like.
