Actually, I'm not even sure if the position did indeed made such a big difference, as the test was for breathing resistance.
I'll try and find out how the testing was done.
Hi Stephan, it makes the most possible difference: imagine that it's dynamic testing: breathing cycles push-pull though the unit, at an immence flow (75l/min)
in vertical position, on every cycle when you exhale, and when you did not optimise your counterlung volume, you have to push a volume of gas 50cm lower than your mouth, or 30cm lower then the center of your lungs!!!
and you mesure the energy (joules) that is needed to transport the gas trough the system....
