...but the thing is....in day to day ops how often do you encounter fully developed VRS?
Mr Vuichard seems to imply it is a regular occurence, hence his crusade to prevent loss of life from VRS accidents.
However, we don't actually see many VRS accidents, there are far more CFIT or power-settling accidents.
Whilst I agree that recovering from IVRS early is a good thing, it is far better to avoid it in the first place by planning and calculating performance before flight and avoiding the conditions where IVRS might occur - it's not difficult to do.
