Right BTB,
If you read the spin recovery procedures in the Operating Notes, it instructs the pilot to make a prolonged dive.
With the longitudinal instability, the aircraft would require more more velocity to buffer against over controlling the recovery and inducing a secondary stall.
In otherwords, the low stick forces and large elevator changes for very small stick inputs make the aircraft vulnerable to secondary stalling in a normal spin recovery sequence.
The high dive speed required to recover from a spin also make the aircraft vulnerable to exceeding the airframe limits by overcontrolling.
I would not be surprised to discover the Spitfire Mk I was cleared to spin after being fitted with an inertial elevator to correct the longitudinal instability.

Look Crumpp, they said: " Allow the airplane to gather a speed of well over 150 mph, (thats not a high speed dive), before gradually easing out... " to reach this spead, thats your prolonged dive.
Recover the spinning, " there is no difficulty in recovering, provided the standard method is correclty used, i.e , full opposite rudder (maintained unter the spin stops) and stick slowly forward when recovery begins.... . " Thats what they (the Pilots) have learned since Flight school.
For all that you are trying to prove there exist advises.
Please do me a favour and make some guestflights in a Glider to understand this practically or in an aerobatic plane. Or look into some youtube videos to get an imagine how this looks like.
;D
