Will the robot be climbing all of the stairs at the same time, or will it be ascending one step at a time? Answer that and you have your answer to which force measurement to use.

Sounds like you will have to calculate both sets of torque then and use the higher requirements for your motors.

The RMF calculation will give you the minimum torque you require . . . but calculating for worst case is very difficult because it includes dynamic torque.
Just calculate for RMF, then add like ~30% more.
