What is the difference between controlled braking and stab braking?

1. They are the same technique with different names
2. Controlled braking applies steady pressure just short of wheel lockup; stab braking applies full brake pressure, releases when wheels lock, then reapplies
3. Controlled braking is for dry roads only; stab braking is for wet roads only
4. Stab braking provides shorter stopping distances than controlled braking in all situations
