Merlin negative G cutout too quick?

Bear in mind that Hawker and Supermarine were ahead of the MoD on aircraft development, both producing what they thought was best and better than the basic MoD specs of the time. Imaginative embellishment is precisely what they did to the gratitude of the MoD. Hawkers had all their experience of the Hart/Fury line from which the Hurricane directly descended (some of those had Merlin engines, do you think they never hit negative G in their life or development?) and Mitchell had all the Se5/Se6 development behind his work on the Spitfire.

Added to that, these aircraft had to be passed fit for purpose by the appropriate authorities, from normal flight to combat.
