When you are new to something, only do something rarely, are limited on having a century of experience where you can do it with your eyes closed, have the skilled maestro touch, OR when one is more based in reality, when you in fact have the proper tools, you torque the band adjusters to 72 in/lbs then back them off the recommended amount of turns. Simple as that. Then you rest easy eliminating all future concern or doubt as to whether the bands are right.
