Eagle,
By "IVR" are you referring to Incipient Vortex Ring? If so, yes there is still confusion, because you then go on to describe a developed VRS.
VRS is VRS, I personally believe there are variables which affect its severity and they range exactly between what you describe and what Nick Lappos describes.
I don't understand why anyone would be demonstrating anything other than a recovery at the incipient stage. I don't even believe that is necessary.
