I have no idea what statistics he is referring to but those statistics seem to be number of fatal accidents......
.......many, many factors come into what the causes of fatal accidents are.
Maybe my experiences are unique and I lived in a bubble during by flying career and my observance of the flying abilities of all the pilots that I gave flight instruction to is flawed because I come from an era when we were trained by sub standard flight instructors, hell yeh that is my problem.. teaching myopia.
Also when I owned a flight school it was just my bad luck to have had an unusually large number of less than stellar instructors working for me.
