I’m kind of tired right now, so I might be missing something obvious, but:
It seems that subjective implication decision theory agrees with timeless decision theory on the problems considered, while diverging from causal decision theory, evidential decision theory, and functional decision theory.
Why do you say that it diverges from evidential decision theory (EDT)? AFAICT on all problems listed it does the same thing as EDT, and the style of reasoning seems pretty similar. Would you mind saying what SIDT would do in XOR mugging? (I’d try to work this out myself but for the aforementioned tiredness and the fear that I don’t quite understand SIDT well enough).
Looking back on this, it does seem quite similar to EDT. I’m actually, at this point, not clear on how EDT and TDT differ, except in that EDT has potential problems in cases where it’s sure about its own action. I’ll change the text so it notes the similarity to EDT.

On XOR blackmail, SIDT will indeed pay up.
