I'm no expert in this department I fly most of the time by the seat of the pants

but I have to agree with mino and ammo on this one...
1) stallspeed of the N1K2 is lower then that of the G10 so it can keep it's nose up longer.
2) N1K2 is a terrific zoomer G10 is not (it's the best climber) Try this test in the TA... fly a G10 up to 400 mph and then cut engine... go in a gradual 2G climb till pure vertical... note how much alt you gain at point of stall... now try the same with the N1K2, P47, P51, F4... you'll notice a remarkable difference. Of course the difference isn't as great at 300 mph but it should still be significant.
3) I know you know this but I'm gonna say this anyway

... The G10 is a very good climber... you should have gone in the 270 mph powerclimb (G10 still climbs at 3500 feet a min)... you would have left the N1K2 in the dust...

IMO against TnB fighters don't go in a chandelle... cause most of them can still catch you early on because they can 'cut the corner...
Just my opinion
