In my eyes the detail or who should have been here or there etc is irrelevant
This incident highlights the problems of having multiple settings which can only add to confusion and the option for a mistake to be made.
That is why we should all move to using a standard QNH and stop clinging on to archaic habits from the past which aviation is great at doing.
Less options less options for a mistake and there should only be two settings QNH and FLs I would also go for a uniform transition ALT/level like they do in the USA
