Sorry for delay.

Copies as in "upload your mind. then run 20 copies of the uploaded mind".

And yes, I know there's still tricky bits left in the problem, I merely established that those tricky bits didn't derive from effects like mind copying or quantum suicide or anything like that and could instead show up in ordinary simple stuff, with no need to appeal to anthropic principles to produce the confusion. (sorry if that came out babbly, am getting tired)
