It does, try some of the license tests where you have to accelerate and then come to a stop again. If you downshift your time would most likely be better.

Yes true, perhaps that wasn't helpfull, although I posted more than just that video.The video only proves that choosing a lower gear adds a braking effect to the transmission/engine, it does not mean you will stop any faster. Once you reach the limits of adhesion of the tires, you have reached maximum braking, whether it's from the brakes only or a combination of transmission and brakes. Just because there is a braking effect from the drivetrain, doesn't magically increase the adhesion of the tires.
It helps you get on the power quicker. Let's say you're going 150mph and the corner coming up requires 50mph. If you slow down in 5th and have to downshift 3 times right WHEN you need to accelerate, you just lost a lot of time vs. downshifting while braking BEFORE accelerating.

Why would you not downshift during braking? Thats like driving 101, thats just regular street driving, not even considering racing.
