That being said, I've never felt that it was restricted under heavy driving. For example, on the track I can slam it from 2nd to 3rd as fast as I can and I don't notice the clutch momentarily slipping (there may be some slight hesitation, but I imagine that's more ECU programming).

I do remember when I first got the car, it did seem like the bite point moved around when I was trying to drive smoothly. I think for the most part I've gotten used to the way the clutch works so it's better now, but 1-2 shift is still the hardest.
I'm the same. 1-2 when driving at anything less than full throttle always seems rough. However, I've noticed that there seems to be a LOT of rev hang which I attributed the jerkiness to. I found that, if I'm not pushing the car hard, I can slow down my shifts and the smoothness is much improved.

Can someone explain the point of this valve anyway?
