I agree with Orion. Big time. We all have a different style of shooting, and needs to further that style, but, except for my buddy J. . . I typically don't ever see anybody holding a bow for ten seconds, or even five (he can hold one drawn all day I think).
It was a nice catchy thing to say for the public viewers, but. . . like G Fred's elephant stance statement in one of his books (where he holds his bow between his legs, facing down, all twisted up and says "this is the test for whether your bow is too heavy"), my response is. . HUH ? when do I EVER shoot like that ?
I think you will know if it is truly too heavy, if you open your eyes.
