Not 100% sure that what you're talking about is entirely the same as what I mean, but I'm at least 78.925% sure - So with that taken into account, FTID methods are almost all BS. Very few, if any work, and even more than that are a huge waste of time.
With that being said, I have met one guy that was able to create FTIDs with a method that he'd come up with and he was actually able to get some successful reships doing it..
He told me the method, because I didn't believe him, but that was months ago and I don't remember all the important details soooo . . sorry
