Helisphere,
Good thoughts, I really agree that the updraft could make things worse. Maybe not VRS, because SWP is strongly influenced by descents. I think you might be on to something.
FAA does VRS testing - no, not required, maybe not necessary.
KMax? Great question! Different flow patterns might yield different/no VRS.
BTW nice excel spread sheet, good work!
