I am a TRE and the last time I was asked by someone about 'the TRE/TRI rates' it turned out to be a second hand question from a person trying to get her husbands earning figures for a divorce! Your questions reminds me of the line in 'Catch Me if You Can' where main character does not know what the jumpseat was during checkin. Whilst I don't doubt your credentials the question posed does.
As a TRE I would expect you to have the details.
