Your understand of ABS is flawed, a good system detects that the wheel is slowing down faster than it can possibly slow down, and should start to release pressure before the wheel is actually locked.

This is why with training a good person can outbrake ABS by a bit because the person can keep it right on the threshold of maxium braking about 5-10% slip depending on tires, meaning the braking tires are turning 5-10% slower than actual speed over ground, versus abs going from below maxium braking and 0% slip back to 15% slip and repeating.
