Also - when the dial is at maximum error, I find that I can't even budge the dial more than 0.0005" by pulling up/pushing down on the table by hand. To me this implies the gibs/rails/whatever are highly snug. Yet the deflection is still here.
Man. Very confusing.
This may be an easy solution!
The different amount of error for each direction of travel is due to loosness of the Gib itself, one direction makes it wedge in tight, the other makes it relax sloppy!
Check the adjuster screw & knotch in the Gib, to see if there is extra slop in the adjuster !
Just Another concept!
