Usually tightening tapered roller bearings involves spinning the wheel slowly as you torque the castle nut to a certain torque well beyond the final torque number.  That is to take all the play out of the tapered bearing and seat the race all the way home.  Then you turn the castle nut backward until its free of the assembly and use a much lower torque setting while spinning the wheel slowly to feel for drag to achieve the final torque setting.  If the wheel drags when you tighten it, back it up and tighten again stopping short of where it was dragging....    You don't want to be too tight because the bearing will heat up and have a short life.  It's not that hard to do correctly with a little understanding of what you are trying to achieve and knowing the common technique that almost all tapered roller bearings employ to get the proper alignment....  It's doesn't seem like a very scientific process compared to a nut with a torque value, but it is a tapered bearing, so even slightly too much torque is not good unlike any other thing you may tighten...
