Default Different size camber shims on L / R side? Odd?

Car was just aligned at the dealer and today I was doing some track prep and noticed that the Left and Right sides have different total thickness camber shims, yet the alignment is even. Besides the shims what else is adjusted to set the camber?

The camber micro-adjustment is at the strut tops.

The differing caster from side to side is a result of the uneven shim thicknesses. Probably nothing you'll feel behind the wheel though.

Seems like a big shim diff, the "micro" adjustment at the top compensates?

Has anyone mapped out how much each shim affects camber and caster?

according to a comment on tarett website 10mm is about 1 degree negative.

im not a suspension guru but could be due to the rubber in the suspension and needed to get the sides same camber?

There you go. For non-monoball setups there'll always be some element of guesswork and change as soon as you track the "perfectly" aligned car. Nothing out of the ordinary there.
