I have seen videos that describe this as the proper technique. One thing I've noticed about my own pedaling is that when I concentrate on bringing my knees up my perceived effort seems to go down but my rpm's go up. Still the best thing I've ever done is to use rollers. I don't know what a good standard is for my age (67) but I can do 130 rpm's without bouncing.
