I agree, all pretty good advice ... however ... not every day is a rainy day ... so (if I were active) I would NOT be building my conditioning platform around "rainy days" ... but rather would just be prepared for them
In other words, because I feel the jenny is best, I would be using that every day I could, and would only switch to the mill on days I had to ... rather than only use the mill because "it might rain" someday. The weightpull harness and flirtpole also comprise my preferred keep. I personally would only use the mill on days I had to.
Don't get me wrong: I have a full mill keep too, that is pretty good, but I don't think it is as good as the main keep I have ... which has no millwork at all ... but plenty of jenny/pull/flirtpole work.

No one is saying there is an absolute lack of propulsion forward on the mill. There is work there. With a hard turning mill on the incline if the dog is only slightly faster than the mill he will move to the front. If he is slightly slower the hook up will get tight the other way.
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
Just for the example, if we go up the escalator that is coming down that would be the same as the dog moving the belt in the opposite direction. Instead of a person pressing down and propelling his weight upward and outward to the next step the step moves away from the foot. On the ground a dog, or on actual steps, a person must generate the power to propel himself/herself forward.
An avid runner will tell you there is tons of difference between running on a tread mill and running down a road. Same with the dogs. EWO
I agree that there is a difference between natural running and running on a mill that is level with the ground. I dont think either escalator example is the same though. But did you say there is propulsion on a hard mill on an incline.
There is propulsion on a mill on an incline and when level. EWO
