It sounds like you expect someone at level 7 or higher to agree with the first part of #6:
I anticipate with less likelihood waking up as a copy that will die soon after the procedure—or for some other reason has a lower amplitude according to the Born rule—as a continuous function
I don’t think I agree with this. If one copy gets immediately dropped into a vat of water and one gets to live out his natural life, I anticipate a 50⁄50 chance of drowning.
I also don’t know why either of these copies would have lower amplitude, in the short period where both are alive.

Can you clarify whether we actually disagree?
