Wrong. As a race driving instructor that's all I have to say.
D'oh! :-)
In areas of heavy braking, that's what I do, too...

One difficult thing with Viper Racing is to try to keep the car straight
when braking. The same thing can be said somehow with SCGT, under heavy
braking.
The best example is at the end of the long, long straight in Viper Racing at
Dundas (well the city track). It's a tricky corner. Your going at 170+mph,
and you need to brake hard for a 60mph corner. Normally if you brake too
hard you will loose it. Sometimes applying a little throttle (let's say
10%input) will help you control your braking zone line, since it will put
more weight on the rear of the car (no sudden weight shifting). This way
you can decide if you want a slight oversteering if you brake too late or a
little push in the same situation. It will help you brake harder, and brake
in a smaller time.
The same applies with GPL, per example into Tarzan at Zandvoort or Curva Di
Lesmo at Monza.
Of course, I might be wrong :)

Great! I need all the help I can GET... :)

Hmm... you should probably write and tell Michael Schumacher since
he's been using this technique for years. (S'true - watch him in slo'
mo' round any heavy braking area and you'll see occasional tyre smoke as
the tyres slightly lock and unlock).

This is not necessarily "rapidly pumping the brakes". Under heavy
braking one will normally have to apply more brake than under normal
braking. And in order to pull off heavy braking one usually will need
to be near the point of locking the wheels. Get to the point of locking
the wheels, let up on the brakes enough to get the wheels to turn. As
the car continues to slow, one can then apply more brake. Again under
heavy braking you are trying to get the maximum amount of braking which
is on the border of locking the wheels. To find the border, you will
often have to cross it and then retreat.
Rapidly pumping the brakes is a "spastic" and uncontrolled method of
braking. It will cause you to cross the border and when you retreat you
move too far away from the border. What one really wants to do is
"touch" the border and stay at that point (but the border is a moving
target, as it moves the slower you get). In other words, explore to
find the border (locking of the brakes) and retreat just enough to be
"in touch" with the border. As the car slows, the border will be moving,
therefore you are always searching for the border. Rapidly pumping the
brake is like a ***shoot. If you roll the dice often enough, you may
just find the border, but once you find it you loose it with the next
roll of the dice. And then you have to start the ***shoot all over
again.

Momentary wheel locking, when braking at the limit, is generally caused by
surface irregularities or sudden weight transfer that momentarily reduce
vertical wheel loading. When the locked wheel regains its full vertical
load, the frictional force at the contact patch increases, causing the wheel
to spin once again.

Sure - I guess it depends on what you define as rapidly...
