Please forgive my made-up terminology below.
Mine is definitely low when it is in the "bi-level" (head & feet) mode.
If it put it on "upper" (head only) mode, I do get a lot more/acceptable movement, but not anything I would call powerful.
I contrast this with my Honda Pilot, which I drove yesterday. On high fan, the Pilot REALLY puts out some airflow. Additionally, it doesn't matter whether I have it on bi-level or upper. In any case, it's great.
So my further questions to all of you:
1. Is the upper airflow much higher if you keep it on "head only" or is it always the same?
2. I know many of you have a Honda Pilot. Can you give me your perspective relative to the Pilot?
Maybe I'll just go for a test drive on a new TCH and try it
