wings thank you for posting this link, never saw it before, helpful. i have tried to explain stacking air several times. i do it without equipment. inhale three times insuring it starts at bottom of diaphram, exhaling as fast and forceful as possible. when doing a fvc test you inhale through a tube and exhale through a tube as fast and hard as possible. i use a four inch long, 1/2 inch diameter piece of plastic pipe. this kind of duplicates the test. i think i can judge how successful i am doing
