Agreed, but he doesn't seem convinced enough to press the point with the PNF when he chews him out for it and shuts down that avenue. The PNF's immediate following action is to defer to the Captain.
Too bad they didn't learn from that little experiment. We used to run my favorite fighter up to 600 KIAS, then set idle thrust and speedbrakes to see how much eyeballs out g we could generate.
A negligible effect would strongly indicate low airspeed.
