I now have the whole trail mapped and published.  I bought a GPS device part way through my section hike of the trail last winter (’15) and initially was collecting only the data that was missing from Charlie’s maps with the idea that he could use it to update his maps.  Instead I have used his data to fill the gaps in my data for the eastern half of the trail.  I will eventually re-hike the eastern half to get a fresh track and fill in any other missing data I can.
