Aloha Artimuse,
Good, better, best.
Doing your exercises or meditations at the 11-1 time takes less energy and generates greater benefits.
Chunyi would say that if you can do it during that time-great! If you have to do it at a another time-that’s good too, as long as you are doing it.
I can't remember if Chunyi felt it was twice the benefit for the same amount of work, or not. Do what you can do and enjoy.
Much love, Shawn
