I am a Canadian born and raised here, also trained in Canada by an experience pilot/instructor which seem to be out fashion these days (trained by an experience pilot/instructor that is).
In Canada, Transport Canada (our aviation authority here) is well aware of the difference between VRS and SWP and so am I. But you are right that the FAA do not recognize the differences.
So I will bow to your great knowledge of the subject and leave this tread and when I retire in 2 years from now I might take the time to read on VRS, IVRS and SWP and try to understand how I have been able to survive 40 years + doing what I am doing without knowledge of this condition called VRS (in it's fully developed state of course)
