^ Nice post. 
This should be stuff thats 101 basic for everyone on this forum arguing about these topics.
This is why I cringe when I ask what someone used to install their ARP studs with and they're unsure or used what they happen to have without calculating the extra torque needed to achieve proper clamping aside from repeatability which obviously changes greatly.
