So what is it- closer to acruator means more or less overshoot?
I got a bleedvalve coming soon for the S13 drifto shed

Closer gives more overshoot from my limited experience of bleed valves, but it may be a case of there is an optimum point so its more of an "x squared" sort of curve?
I thought it was the other way round, as I seem to remember an article many moons ago, where they showed you how to get a big spike by having a huge length of hose (coiled up) between the turbo and bleedvalve, by varying the length, you could dictate the overshoot

.
Makes sense as it would take longer for it to fill the pipe, but its just not how it happened on mine, but it might be to do with the speed at which the gate is moving too?
Im sure Stu can give one of his nice definitive technical answers later
