My jig is clear of the strings, both in tune and when detuned, it is essential that the guitar is not moved during the test, this negates all findings. The front of my jig has a single standoff identical to the ones you can see on the rears

I find anything under 0.4 degrees to be very stiff and muddy in sound

0.5 to 0.9 i find to be a good compromise between stiff and vibrant, most manufacturers guitars fall in this range.

Dont forget measuring directly of the bridge will have a different reading as you are also reading any glue creep that may be happening as well
