Thanks I'll keep that in mind. Honestly my motivation on working on this kind of stuff was Wigner's friend since they also seem to have a conditional time evolution there.

"From the friend's point of view, the spin has collapsed into one of its basis states upon his measurement, and hence, they will assign to the spin the state corresponding to their measurement result: If they got 0, they will assign the state ${\displaystyle |0\rangle _{S}}$ to the spin, if they got 1, they will assign the state ${\displaystyle |1\rangle _{S}}$" - wiki

Also my bounty expires soon (24 hours)... So maybe you could write your thoughts? (And put some sort of disclaimer?)

4 hours later…

@MoreAnonymous not really on the computer at the minute, I'm afraid
Although for Wigers friend and the like, read things about reference frames
