Total confusion when one adds the FAA PTS requirement for CPL students "recover as the stall occurs" which is very fine line, past stall warning before nose drop. Hard to get students to focus on anything other than finding this "sweet spot" when practicing stalls. They should have practiced and been tested on both a full stall and recovery + recovery on first indication of stall. The focus should be on stall recovery, not how to identify the very exact point of "stall" - which pilots and engineers would probably disagree on when that actually is.
