That's the point: even in the past a lot of authorities, I am talking about medical for example, were understanding in different ways the same rules. This is again the case, where some of them won't change their procedures just to adapt to something they don't really understand or agree with.
And talking about TRE I do confirm, it's much better filling the forms the day before and get there just with that paper to sign: it makes them happy, since they save time, and my life easier!
Fortunately my licence is due to expire at the end of February, so I still have some time to sort it out. I asked him to check the briefing, let's see if he'll be that kind. Otherwise that's it, I'll switch to my national authority, I know for sure they don't require any briefing. Other option would be going to a TRTO in UK and have my revalidation done with a UK TRE, but way too much money, no thanks.
