As for the original premise of this discussion, the effect of a hard buffet for stall warning on turn performance:
Quote:
Aircraft with shallow stick force-per-g gradients
can feel dramatically sensitive if your muscle
memory expects greater forces. Even
experienced aerobatic pilots stepping up to
higher performance aerobatic aircraft usually
find themselves pulling too hard, detaching the
boundary layer, and buffeting the
aircraft—especially in the excitement of
aerobatic competition. This is seen from the
ground as an abrupt flattening in the arc of a
loop, and from the cockpit as a sudden g-break.

In the absence of boundary layer devices, buffeting will increase the radius and decrease the rate of a turn. The harder the buffet and larger the buffet zone, the more dramatic the result.
Stall warning is another engineering trade off. If you produce an airplane with large amount of stall warning, it will not achieve best rate of turn at 2D CLmax. The less buffet with smaller buffet zone and less stall warning, the closer to 2D CLmax the aircraft can achieve best rate of turn.
