Keep in mind that is the torque using the specified tool. Not the actual tension on the belt.
Not sure if it is new or used. That being said I just use the 90° twist at the 1/2 way method an not any special tool or toque vale. Have done that with a used and new belt and never had an issue. This is one of those don’t over think it things. It’s a belt. Tension is only to make sure it does not slip but I know you are more than capable to tension a belt so I am preaching to the choir on this one.
