The Gazelles did thousands of EOLs/full down autos in the Brit MIl, it was the sport of kings.
Most guys I taught on the instructor's course had flown EOLs in Gazelle during basic training but most of those had the assistance of the Hand of God from the instructor at the time. We had to build their confidence and skill to a point where they could not only go solo for EOLs but be able to correct student errors.
Valid point about the relative training systems but, while there are a lot of training sorties (often to keep current at the myriad of disciplines), a great many are operational flights (the Military equivalent of earning your company money).
