So long as you have equal spacers on each side of the axle, the chainline will go relatively unchanged. An extra 1mm spacer on the non-drive side will push the chainline .5mm outwards, and vice-versa.
Don't shoot me for asking dumb questions...but, if you get both chain rings within 1mm of true "chainline" alignment, and they sit some 200mm (of free chain) apart... isnt that something like under .4 % variance? I dont see how this hurts the chain.... measurably. I mean chains are designed to survive slight misalignment... that's what makes them so great!
Just wondering.
