What it shows is where the majority of spins occur. The main thing it points to is the fact that the majority of occurances happen at a time where learning how to recover a spin is irrelevant. You don't have time.
Spin avoidance is far more important.
You could be an amalgamation of John Farley, Eric Brown and Luke Skywalker but if you enter a spin at 5-600ft AGL you are stuffed.
Very few spins happen in the cruise or at altitude that aren't done on purpose.
Training needs to be fit for purpose and teaching actual spinning does not help you to be a safer a pilot. The stats prove that.
All it does is to put the poor old FI at increasing amounts of risk as BEagle proved in his post about the imbalanced fuel tanks.
If you are going to be flying aero's and will be pushing aircraft to the limits, then of course spin recovery is vital, but for basic training........Nope, not necessary.
