Jeff! (How you been man!)
You know as well as I that Grant said that that vent length would be longer because the enclosure would be smaller (for the same alignment).
Yes vent length is related to enclosure size and tuning frequency as you said but Grant is keenly aware that the enclosure will be half the effective volume in an isobaric setup while you and I are only suspecting it.
If you halve the enclosure volume then in order to maintain the same tuning frequency you must double port mass which would require a vent more than double the length since it will still only have two ends which also contribute to effective vent mass.
