I can't tell you that.
That's why I suggested to test your brakes in a parking lot to see what they do with uninterrupted application. Mark the distance it takes to stop from a predetermined speed.
Now do the same pumping the brakes. You may be surprised that pumping the brakes may indeed alter your stopping distances unfavorably.

During a panic stop on the highway with limited distances to stop, you may or not have the luxury of pumping. Most panic stops involve single depression of the pedal.
Remember this is not like you are driving on wet or icy surface.

You have taken your eyes of the road, the car in front of you has come to a stop, you see his brake lights, and you go for yours.
What will the car do? What did it do in the parking lot? That is more information than my brain can process in a millisecond.

It does help knowing. It may save your car and your life.

Class dismissed!
