The Spitfire, which had a relatively low - compared to other fighters - calculated AR point of about 510 mph IAS iirc, at which airspeed it is supposed to roll in the opposite direction. The reason for that was the wing's structural design, which wasn't very stiff. But that wasn't that much a problem since the plane was limited at around 450 mph IAS in dives.. iow, you were beyond the safety limit when this happened.
But since AR is not a on/off function but sets in gradually, its a good indicator of how high speed (negatively) effects the rate of roll.

I'm not an expert, but is this the same thing that happens currently to the BF110 when you go beyond 500 kph. At 550 kph the plane is almost out of control with its twisting and drifting.
