Sometime back someone had mentioned something about the reason for the trailing plug having a smaller
hole than the leading plug.  I can't find that note.
Anyone have any info on this?

Has to do with the pressure differences between adjacent chambers
as the apex seal passes over the hole.
The larger the hole the more the leakage from one chamber to the next.
