Have you experienced creaks when arms were loosen? BTW. I never felt like crank arm was loosen or wanted to fall off, just creaks mainly.
SRM provides recommended torque values. This is for both the crank bolts and chainring bolts. Using different torque (especially the chainring bolts) will affect the accuracy and consistency of the power values. I always use a small torque wrench when changing rings and larger torque wrench for the crank bolts. It did creak a few times early on.
