In addition to doing it by eye, the belts always track to one side or the other of the pulley as they spin. When we tighten the belts, we sometimes spin the drivetrain by hand to see which side the belts move to and then tweak it the other way to fine-tune it.

Also, I've seen some wheels that were fairly crooked (I'd guess 10-15 degrees eyeballing it) after running matches or practice (usually caused by a bad job tensioning and/or one of the tensioner bolts backing out), and the belts seem fine afterwards, so it doesn't seem to be a very big deal.
