Same with us on an escalator. If we ride it up there is no real output other than standing upright. If we run up the escalator we get there faster but with less work than if we ran the steps generating our weigh forward/upward. If the walking surface is moving (escalator/treadmill/slat mill) there is not the same amount of propulsion required to generate movement forward.

That goes for any mill of any type. Any time the dog is carrying his weight and propelling his weight and the time/distances are the same the dog propelling his weight will benefit more. EWO
I dont see how running up an escalator that is already going up is the same as any kind of mill. Dogs dont move in the same direction as any mill they are working.
