Aren't there two questions here?
With respect, no there are more than 2.
Here's another...
A risk assessment is carried out to determine the value of any given training exercise post-licence issue against the hazard posed by carrying out the training.
This was done with spin training 25 years ago, due to the deaths each year to students and instructors. The assessment that said that the post-issue value of spin training is less than the hazard of carrying out the training has proven to be quite correct. There are VERY FEW deaths in SEPs caused by accidental spins. I deliberately exclude gliders and microlights from this - we're talking about PPL SEP training here.
What we DO need to concentrate on is better weight & balance and meterological training. It seems to me that controlled flight into terrain (usually in bad weather) and accidents caused by badly loaded a/c are the major causes of serious injury/death accidents today. The majority of UK GA accidents are caused, according to the CAA, by poor decision making. Thus, the accident happens even before the aircraft leaves the ground!
