Spin recovery vs tail design

I guess pretty many pilots here have flown the ASW-20 - recovering it
with setting 4 (zhermal setting) with a medium to rearward CG ca take
up to 2 turns, but with flaps 1 (fully negative) recovery takes at
maximum 0.75 turns.

Not surprising at all - it would surprise me if anybody really wants
to teach this. Lets see -

- A desire to teach a standardized recovery
- Don't distract people with grabbing for a handle while under stress
(or if not stress just physically being thrown around a little)
- Likelyhood of grabbing the wrong handle (esp. if transitioning from
another ship) and just moving it (i.e. opening full spoilers)
- With full negative flap what happens to increased likelihood of
entering another/reverse spin if the pilot recovers too "hard"?

Wouldn't the chance of another/reverse spin be even greater in a
positive flap setting if the pilot recovers too "hard"? What I noticed
in my ASW 20 and my ASH 26 E is going to negative flap immediately
stopped the spin and there is nothing to "recover" from except a "mild"
nose down attitude. I haven't tried waiting more than a half turn;
perhaps waiting a full turn or more might be different, but I'm only
concerned about immediate recovery attempts.
