I'm sure maybe my foot has slipped a small handful of times in my life as well, but it has been very rare. If you were just a hair too high or too low it would grind anyway. So I think I did alright considering that. I usually can barely feel it going into gear I get it so close. This is especially true on the bimmer. holy god that car has a smooth trans.

I always blip the right amount, and then usually after I get the gear selected I'll blip a second time to get it back for releasing the clutch (if it's necessary, hard to explain I do it by feel sound and intuition mostly, you know how it is). If I happen to be braking and need to down shift, I will do a full heel-toe blip, but I'm not a very agressive driver, and very rarely need to do that on the street. I never never never downshift without matching the RPM on the primary and then let the clutch jerk the car to slow down, hate it when people do that.

Don't blip on an up shift. I know it is tempting but it is backwards to what you want to achieve. When down shifting you are going from a gear with lower RPMs to one that is going to bring them up so you have to blip to rev match and speed up the engine closer to where you want to be. When up shifting you are going from a gear that is in high RPMs into one that will start out much lower. You actually want the RPMs to drop a bit in the up shift to be closer to the synchros speed in the higher gear.
Make sense?
