Gadget freak,
I was looking at my own copy of the POH, and it's a few years old. I daresay that bulletin came out more recently, and I never got round to paying for the updates you can get from Robinson. As you say, it does seem pretty clear.
idle stop,
It does indeed say what you quote in the limitations section. However, the instructor is PIC, so whether the student has the required number of hours shouldn't matter...should it? As to whether they'll learn anything, IMHO it depends on the student, the precise conditions, and the exercise being taught, and is a whole other topic.
Anyway, people, thanks for the info. I'll read up-to-date info in future. I can't help thinking they've overdone things somewhat; I don't seem to find flying the R22 in 25 kt winds to be a problem. Or maybe I'm just getting overconfident.
