If memory serves me, 100kts in the Hunter is centralise and wait. Maybe that is the pause noted on recovering to a vertical dive and completing the manoeuvre.
To keep a fast jet display within the boundary of a small airfield is not possible - so positioning manoeuvres will be over assorted bits of the surroundings.
A bit of flap is 'de rigueur'
That will do. Mustn't speculate.
