I do NOT profess to be an 'expert' and am dubious of those who would consider themselves as such. However, the Standard Stall Recovery I advocate is that which I was required to teach for my CFS A2 QFI test assessed by a CFS Exam Wing examiner, to brief at a FI re-validation seminar asessed by the ex-CAA CFE and to teach to a CAA Staff Examiner on my last FI re-validation flight test.
If it's good enough for them, it should be good enough for others, in my opinion - and it's worked fine for my students for the last 15 years.
I guess we're actually in agreement, it's just the wording that differs.
