It's actually not that critical in my experience (the chain was ridiculously loose when I got it and rode it for 700 miles, didn't really notice much of a difference when I tightened to within spec). Once you get used to what it's supposed to be, eyeballing it is quite easy, IMO. You just don't want it so tight that you snap the chain, nor so loose that it flies all over the place, hitting things. Kind of reminds me of the elaborate apparatus people use to align their rear tire (not that this is elaborate by any means, just that it seems unnecessary to me).
I never did understand that elaborate craziness of aligning the rear to the front. Your rear needs to be in alignment with the swing arm pivot. I just measure center of pivot to rear axle center on both sides with a tape measure and you're done. If it does not align with the front after this then you have other problems like a tweeked frame or forks.
