I'm not sure how any table can be reliable. Unless you know for certain that X brand only always uses Y-sized bolts that are made out of Z material. Aren't torque specs at least partially (if not mostly) contingent on the bolt size? And then sometimes torque spec might be also partly contingent on what the part is that is being clamped and not what the clamp and its bolt itself can withstand.

The Park Table, isn't it really out of date?
This is the clamping force table for tightening your saddle rails down in the seatpost's clamp? Any of these brands really still in play on any newish bikes? Ranges by brand from 6-34Nm .. seems really wide spread.
