I can't see airspeed being a problem there.
The Hunter is a swept wing aircraft, and indeed I'm sure the TP's are right about turn radius, when the aircraft is flown accurately on the light buffet.
However, should the pull be continued into heavy buffet, which would be easy to do, the aircraft will continue to turn, but energy is being washed off at a very rapid rate. The available speed, hence G, will be less. The only safe way is to keep pumping energy in with max thrust, and keep flying the light buffet. Jesse Pinkman gave a very clear explanation why earlier.
