As I said before, my theory is far from complete - it's more a list of facts than a structured model. It only describes those things that happen in typical human life. It may not be extensible to events like loss of consciousness, let alone cloning. In fact I've been pretty much convinced by this whole thread that my naive model probably can't be fixed and extended to describe the entire space of physical and experential possibilities. I'll drop it happily for a better alternative - please give me one!

I think we have, at least in sketch form - here's Alicorn's nutshell summary, and here's mine. Both of our theories, if they are distinct, fit this intuition of yours - that a person is not destroyed and a new person created after a spell of unconsciousness - better that the thread of consciousness approach.

As for the rest, quite frankly you should expect to get weird results in weird situations like duplication. One weird result I expect is that, if you are duplicated, there will be two people afterwards, both of whose experiences suggest that they are DanArmak.
