Don't worry about letting off the brake a "little" bit. You can't tell that I do it while in the car, but data shows that I do. I have heard that nearly everyone does a little.
I actually heel and toe constantly, or at a minimum rev-match, even during daily driving. I find that it is impossible to drive one way on the street and a different way on the track. The goal is to develop good habits that you perform subconsciously. It is too hard for me to do that unless I am "always" driving the same way.

don't worry about syncros . . . your car is modern enough that they will, for the most part, take care of themselves. Rather, you are worrying about matching the revs so that your car will not be upset by you "chirping" the rear wheels when you downshift, which can throw you into a spin, or at least make the car unstable.

do you guys blip when the stick is in neutral or in the new (lower) gear?
e.g. on a 4 to 3 downshift, do you just brake, clutch in, move to 3rd, blip and release clutch?
or do you actually pause in neutral and then blip and then put stick in 3rd and release?
i do the former and it seems to work fine. Should i be doing the later?

Read post #51, then watch my video clip again. You declutch. A split second later, the shifter is moved to the intended gear as the throttle is booted. These two happen simultaneously. A split second later, the clutch is re-engaged. It's over in a Mississippi!

The block of wood idea taped to the gas pedal sounds like a good idea to practice on the street.
I can't think of any other way to have the brake and the gas be close enough to make practicing on
the street feasible.
