Yeah, I actually mapped it out using Excel. For the ones labeled "duplicate", there were two versions of the channel on that list so they may just be the same channel duplicated. FYI I am on the east coast.
JMaddox extras (missing in Local/East/West):
Anime All Day (duplicate?)
CSI 2
Love & Hip Hop 2

Funny now that I look at this more closely it seems that all of the JMaddox extras are "2" channels and some duplicates. The only exception is for Movies for Gamers. JoaGomex on the other hand seems to have three extra channels (Ink Master, Oxygen True Crime Archives, The Wild West). The only discrepancies between the east and west lists are news channels, as expected. Also as expected is that Local matches East since I am on the east coast.
