They likely stuck 11.3 into that context back in the 2017 posts to make the DS and us assume that it was a date, so that we wouldn't find out about the Law of War manual so soon. But even while being posted in a random (misinformation) context, Q still references 11.3 as the first marker where proof will begin. So even though in the context that 11.3 was used at the time was deceptive, the clue was still hidden in plain sight. It's probably the very thing that Q means when he says "you have more than you know."
