Ive heard that as well.My understanding on this point is that Paul, advises that a cloth in the exhale loop after it has absorbed any lung butter or water, will expand and weigh heavier and will therefore press down on the inhale lung beneath it and affect the WOB.
However IME it’s not the case. And that cloth is typically damp when I’m finished my normal dives so it’s definitely picking up the moisture
