Thanks for your excellent reply Jay!
I've actually never used my 'new to me' second-hand Snap-On Valve Adjuster
tool yet (my car's still apart). But I did back-off one rocker lock nut by
.010"
(using a feeler gauge) then it took 1/4 turn of the Snap-On knob to tighten
it back down. That's how I got 1/4 turn equals .010".
When I do all my rockers for real - will let the list know my findings.

knob of the Snap-On (V-21A, V-21B, V-21E, V-22, V-22A) Type valve adjust tool
would equal 1/4 of 30 or 7.5 clicks on the 'Clik-adjust tool.
My calibration of the 'Clik-adjust', for my '64 TR4, using the "method to
find the number of clicks required" on the 'Clik-adjust' package, comes up with
7
clicks for a .010 inches [.254mm] valve clearance . I don't think "on the
ClikAdjust each 'click' equals .002" is accurate on a std TR four cyl engine. I
think each 'click' = .0014 inches on a std TR four cyl engine. I've never used
a Snap-On type valve adjust tool without also using a feeler gauge.
