Then eliminate the 'factors' you have control over. Like a precise
calibration.

That is fine but if the precice calibration only corrects 10% of the problem
you need to learn how to make compensations to remedy the problem.

AND going back to my original points to the OP, dial calipers are good for
measuring and setting up equipment. The results of using that equipment is
not guaranteed to give good results when using wood as the material to
construct with.





Including but not restricted to, is your table flat, is your stock
perfectly straight, are you working with soft or hard wood, is you blade
"sharp", is the surface of your table smooth, and the list goes on.

All variables that effect final result. Which of those do you have
control over?

All of them if you can compensate, but for instance a precicely calibrated
saw will not eleminate tear out on the back side of a cut. There are other
factors to consider to minimise the tear out. Excessive tear out can ruine
a joint and technique can certainly minimize tear out. For instance when
cutting a 45 degree miter on your TS if you have the miter gauge clocked to
45 in a particular direction it prioduces a better/cleaner cut than if you
clock the gauge to 45 degreesin in the opposite direction. This all falls
into technique and no amout of precision will make both setting equal in
results on a consistant basis.
