offset bushings

YAHBUT, to what/whos specs was it alligned. And the tape test is only good enough to get it to the alignment shop.
Ok, causes for wandering,with all new high-quality parts are, in no particular order:1)Tires, 2)alignment, 3)Sector-shaft adjustment, 4)roadsurface, 5)atmospheric conditions, 6)rear suspension, 7)shocks, 8)other.
Where oh where do those aggravating smiley faces pop up from?

When I took it to tire discounters I told them to use the "granny" specs on the Skosh chart lol What's sector-shaft adjustment? Also I have air shocks installed in the rear, could that throw it off as well if its not the same psi as when I had the alignment?
