What do you mean when you say inverted the sense direction?
The at rest reading will vary with temperature. I suspect that something is still off with your mechanical design, you should have a wider range of tuneability.

.... They vary from .01 - .022 mm. I thought from what I read on the sales slick they were suppose to be around .0003 for there deviation. .....

Please note that no matter how heavy the rails and how light the head, there will be deflection. Conversely, any touching of the head to the build platform will produce deflection. The best you can do is have consistent deflection which you can compensate for.

Indeed with such 8mm rods more than 310mm in length (bed) and a 1.1Kg mass, the plotted bed map will have a nice shape far from flat even if the bed is a perfectly flat 8mm thick MIC plate !
Deflections are in 0.1mm;

There were area's that would spike up and move around with multiple probe attempts. I have been tweaking and getting those reduced. I finally finished designing new fan guides that will also hold the BL Touch so I can compare probing system's map results.

Underbed sensing is really only suitable for stationary beds (think Delta's). You can always put a piezo between the carriage and hotend assembly.
Works flawlessly on my P3 steel :
