I'm thinking a trip over to the old guys at academics is in order, since they should have the reference for why our FTI says what it says.
From an outsider, with no knowledges of the FTI updating/errata process:
Since we cannot seem to find any reference to it other than TW pubs, is it possible that perhaps it was supposed to be stricken from the FTI, but just never happened...and has not been questioned by anyone within the TW until Flying Low's post?
Please share your findings, Gatordev.
