Normally, there should be about 1/2 inch between the resting position of
the pedal annd its thrust position (completey up. This is for preventing
continuous fricton inside the clutch.

Need help figuring out what to MEASURE when adjusting a self-adjusting
clutch pedal bolt.

I've adjusted the bolt all the way in, half way, and all the way out:

No matter whether I adjust the bolt all the way inside the clutch pedal
(turning it CCW facing the pedal like a foot would).

Or if I turn the adjusting bolt all the way out of the clutch pedal
(turning it CW).
Or halfway between...

I don't feel any "slop" anywhere (e.g., between the rounded tip and the
master cylinder piston cup). The *feel* of the clutch pedal engagement
changes drastically between all the way in and all the way out though.

But clutch pedal feel is not the question (mainly because I don't know how
it "should" feel). So the question is only about what to measure, and how.

The question is only about WHAT to measure with a ruler and how to measure
it.
