BTW, I think I exaggerate a bit. For 40 mph, I am probably on 2500 on 4th gear or 2000 rpm on 5th gear. However, just to illustrate the point of braking...

Let off the gas completely. The car will be slowing down by itself because of the vacuum being generated in the pistons. This is called engine braking (truckers: jerk braking). As you approach the red-light, supplement with your brake to slow down. Just before your car would start jerking ("engine overloading") shift into neutral and come to a complete stop.
I would not even try to engine break on a flat road with this kind of method. People would simply think you are a jerk reving high to stop. I know truckers do that because of their heaviness on their vehicle, but I have seen roads into some small towns specifically forbid truckers to do engine break because it is very loud and annoying.

That way you can throw in a smooth series of shifts (5 -> 4 -> 3 -> 2) while braking. Keeps you from having to rev the motor so high.
So, even without heel-and-toe, to maintain gear in slowing down, you can still do the following:

1. brake the while clutch is off
2. until rpm is low enough (overloading), shift down and blip the rev to match the lower gear
3. release the clutch and continue braking
4. repeat step 1 to 3 until you come to a complete stop

Of course, using the heel-and-toe to perform these steps will help a lot. In your previous posts you mentioned that in Germany if you hold the clutch during braking during driving tests, you will lose points. Does that mean that it is a requirement for drivers doing manuals in Germany must learn heel-and-toe to do a correct stop?

BTW, if heel-and-toe is not done right during stopping, it looks very strange from other people's point of view and not very smooth....
