You read that here? Well don't believe it. Failure to torque the arms sufficiently is (or was) a major killer of cranksets. The problem is a lot worse with tapered BBs, but affects splined BBs too. Proper torquing of the crank arm bolts/nuts is arguably the most critical application on the typical bike. Right after it is the BB, but again, that depends on the type of BB.

For a HollowTech II, most of these issues go away.
