Does the piston return to its beginning point with each cycle? If so, at least a complete loop is covered which is the requirement. The piston would return to its original position many times; in the case of the lone popper, it would be upright, so that gravity pulls the piston down. We would be looking for an average over many cycles rather than attempt to extrapolate from a single cycle. Eric
