Certainly agree with those sentiments Genghis,
As far as:-
However what caught people out was the fact that the rate of spin rotation increased when anti spin technique was applied, prior to the spin stopping
This is a known characteristic of the spin in most aircraft that spin properly, and pointing this out should be part of the spin training.
Also, WRT to :-
instructors should make a point of demonstrating how little forward stick/ yoke is required to actually unstall an aircraft. The full-power and shove the stick/yoke forward is over-dramatising what would otherwise be a fairly gentle and underwhelming recovery. Then using power to minimise height loss.
Certainly I teach, and
AFAIK most
UK instructors move from full stall to recovery at the incipient stage with minimum height loss, and the emphasis there is very much on a
small check forward to unstall the aircraft.
