None of those dictate the LTA. The LTA is what it is, the amount of wealth that is attributed or earmarked to you if in an unfunded scheme like AFPS, or however much you have within your SIPP (and that will change daily).
Then (and everyone's will be different), and however you draw that wealth whether EDP, PCLS from your SIPP, annual income etc.. all will be benchmarked against your LTA.
So, none of the 4 in your list get used to determine your LTA. Rather, what your LTA is (voxpop posted a summary of that) determines how much money (from those 4) that you are entitled to, or can draw.
