Will try to focus on the issue through testosterone haze.
As an active racer and CFI for almost 30 years, I have taught countless
courses in racing to new and not so new pilots. Final glides and
finishes are an important part of this teaching.
That said, consider the scenario in which Joe Racer Newbie is trained
and performs satisfactorily in the training course under low stress and
out of the competition environment.
He is then signed off by someone as having been trained satisfactorily.

Now put him on his first marginal final glide where he has not yet
developed the complex energy picture and blows the finish , stalls and
spins in- fatally.
Do you not think this person who signed this pilot off as trained is
going to be at serious risk of lawsuit from wife or others?
Are you volunteering to take on this duty?
