"Dern tight" is exactly right. The seatpost on my domane asks for 7nm, and I was astounded how tight that is compared to how tight "derned tight" feels. Gettin to 7nm with a torque wrench took a lot of effort, and I'm no wimp when it comes to these things. For me, durned tight for the seatpost ends up being about 5.5nm. 6 is another 1/2 to 3/4 of a turn, and 7 is another 3/4-1 whole turn beyond that! Holds fine at 5.5.
