Dunno, mate but you have gone off at a complete to tangent to the original question!!
The CAA stance on revalidation by experience is that it should not be charged. If an examiner does not like the fact that to be an examiner they have a responsibility to ensure they understand all of the standards then they should give up the authorisation and concentrate on something else. Being a professional and embracing the responsibilities of the role should have nothing to with money.
