Shifter Feel

What works perfect for me is stepping on the clutch feeling the moment it engages then click it into gear. If I wait for the clutch to be depressed all the way down it tends to be notchy for me.
In fact, in my super responsive miata, I always applied a mild force on the shifter towards shifting out of the gear when I depress the clutch. The driving torque from the engine will generate enough friction to keep the synchro hub locked. As soon as the clutch hit the disengagement point, the friction was gone and it felt like a gate open and the shifter dropped out of gear. This gave shortest delay without rush to shift smoothly on the super responsive car.

Shifting is only notchy for a short while, after a few miles its smooth, is it more forgiving when its warmed up? This change obliviously has nothing to do with me changing my technique.
Like I've said before, when engine oil and transmission fluid are cold, they are thick and therefore engine and tranny input shaft speed drop much faster. The key is to change your shift timing for the 1st mile or so to lift less and later. You don't need to rush the shifts. Just lift less and later for the shifts. When I do that on my AP1, my shifts in the cold are just as slick as both engine and tranny are at operating temperature. When you get the revs right, you don't really need the help from the synchros even in the cold. Like I said before, I can even upshift without clutch or grind or resistance in the cold for illustration. That tells you how little I rely on the synchros.

Are you referring to when you let the clutch out, after you have selected the new gear? because I get that too from 1st to 2nd. I'm thinking it's the clutch delay valve throwing the timing off, but I don't know for sure because this is my first MT car

Correct me if I'm wrong, but I think CDV only affects high rpm shifts in racing condition. I think it has little effect on normal driving if you get the shift timing right.
For example, when I push the clutch down and I feel it disengage, I start to move the shifter into the neutral gate as I continue to push the clutch to the floor. Then as i'm pushing the shifter into the new gear i'm already starting to bring the clutch back up, and by the time the new gear is selected the clutch engages and I continue to fully release the clutch. This is a lot smoother than my previous granny shifting technique
I hope i'm doing it right
