Sadly, many Examiners have demonstrated a total lack of understanding of the revised ANO requirements of NPPL revalidations. They should reasonably be expected to keep themselves up to date by reading AICs, at the very least.
If someone wishes to be an Examiner, they should first look at their business case. Fleecing people for a few seconds with a pen is entirely unreasonable - and was actually prohibited in the pre-€urocracy days of BX examiners.
