You are forgetting that as speed increases so does lift. As the main
source of lift is forward of the elevators as lift increases so does
the nose up tendency.

Stop for a moment and think about what you wrote. CL is aft of CG (must
be for it to be "nose heavy") -- and besides, CG aft of CL loading is
unstable and unsafe.

As the lift increases with airspeed, the CG doesn't change, so the nose-
DOWN tendency increases with increased lift. That's just the opposite of
what you wrote.

Also, if nothing else changed, a tendency to point nose-down would
depress the effective angle of attack of the tail, creating more down-
force at the H-stab. So what would really happen is that the nose would
tend to depress a little with increased speed, until it was counteracted
by the more negative angle of attack of the horizontal stabilizer; It
would reach a point where the forces were balanced.

For maximum "slippery-ness", you want the surfaces set up so everything
is more or less neutral at the speed you're intending to go. To repeat
my old saw, anything sticking out in the wind is just an air brake.

For a given target speed, these high-end racing guys aren't going to fly
anything less than a fully optimized aircraft. They'll settle for less-
than-optimum at approach speed to get the extra knots. That's a given.
