lightheir - not missing your point at all. I have run on enough that there are varied intensities across treadmills and I can identify the major outliers (significantly fast or slow). However for me any treadmill feels harder. What about me makes that so and others perceive the opposite?

Airflow is something that I am going to play with this week and see what that does.
