Neither you nor anyone else here has any idea what is in Andy's display authorisation.
Thats not true is it? The AAIB special bulletin gives the following:-
He held a valid Display Authorisation (DA), issued by the UK CAA, to display the Hawker Hunter to a minimum height of 100 ft during flypasts and 500 ft during Standard3 category aerobatic manoeuvres.
You have mentioned motives before, perhaps someone is just trying to understand why, on a hot day with full tanks on display No.1 you might start low? Why try and blur that?
All this talk of "you can start from 100 feet and pull up into your figure" is just poor because how is one assessing that? I don't see how that methodology allows for very accurate / consistent entry, let alone how the FDD or DAE does the same when trying to fulfill the requirements of their roles. As indeed it proves given what has followed.
Its fair enough to defend a friend or whatever but to actively ignore some fairly obvious elements doesn't make you professional at all.
