I think I'd do the eyeball test.
Put the chain on the middle chain ring and cog (4th, assuming you have a 7 speed rear)
From the rear, sight along the chain and see if it angles to one side or the other.
IF it seems close, repeat, using 3 & 5 and see if they look equally bad.

BTW, could the chain rings be installed "flipped"?
