*Position of wear is not considered in such studies.
*Fitting height is only marginally controlled in this study
*Patient acceptance is not necessarily linearly related to "highest level of distance zone area in square millimetres".
*New designs arrive sooner than poor Dr. Sheedy can publish.
*Material availabilities and choices may well mitigate/exacerbate problems with a given design.
*And again, we're dealing with uniquely different human visual systems, personalities, and environments, and not the Hubble Telescope.
In other words, you are dealing with way too many variables to ask such a simplistic question as "which progressive is better" for me. Only God knows that answer.
