The parents that you referred to are now at 17 and 22 points, which seems a bit mad to me. Spotting the errors in P&R's reasoning isn't really the problem. The problem is to come up with a general decision algorithm that both works (in the sense of making the right decisions) and (if possible) makes epistemic sense.
So far, we know that UDT works but it doesn't compute or make use of "probability of being at X" so epistemically it doesn't seem very satisfying. Does TDT give the right answer when applied to this problem? If so, how? (It's not specified formally enough that I can just apply it mechanically.) Does this problem suggest any improvements or alternative algorithms?
Again, that seems to imply that the problem is solved, and I don't quite see how the parent comments have done that.
I presented a solution in a comment here which I think satisfies these: It gives the right answer and consistently handles the case of "partial knowledge" about one's intersection, and correctly characterizes your epistemic condition in the absent-minded case.
