Using the RE of 1.28, we get dpw of 8867 using the calculation. The rules show a dpw of 3120. My question is, would the fact that the warhead is a shaped charge inside a titanium form to direct the charge forward be the reason the dpw is lower? In my mind, that sort of makes sense, but does make dpw calculation just that much more complicated.

LX-14 is used in the later models of TOW, the BGM-71A/B (which is most likely what is depicted in the game book) used 2Kg of Octol which is 1.16 which gives you 5357 Dpw, still doesn't come close to the published number, but I would guess based on the time frame the correct information would have been difficult to find based on the bibliography listed.
As you ask does the shaped charge account for the reduced Dpw, most likely this could answer that question.
