Since there is no where to read G force unless they had recent aerobatic flying that would be very subjective.
So true, but not a problem
IF you are below your cornering velocity. If well in excess, I would think that pulling throttles to idle and putting out speedbrakes would make a substantial improvement in pullout altitude, even if at the expense of maximum g load.
The most valuable seconds in a dive recovery are the first few seconds. Delay in getting max g on will cost you altitude.
We haven't even discussed what you do when you realize that you were successful and will miss the ground.
