I have used this formula:
 
Distance you want to move POI (bullet impact) / shooting distance x  distance between rings (c/c)
 
= shim thickness.
 
(All measurements in same units)
 
I have used this formula to determine which pos-align inserts to use in my Burris Signature Zee rings. (I prefer those rings instead of shimming individual bases/rings)
