I have actually done the math for simple toy cases like Bell's inequality. But yeah, you're right, I'm no expert.

Different parts of what?

I have a related degree, if that's what you are asking.

I'm yet to see anyone writing down anything more than a handwaving of this in MWI. Zurek's ideas of einselection and envariance go some ways toward showing why only the eigenstates survive when decoherence happens, and there is some experimental support for this, though the issue is far from settled.

Precisely; the issue is far from settled. That clearly doesn't mean "any handwavy speculation is as good as any other" but it also doesn't mean "speculation can be dismissed out of hand because we already understand this and you're just wrong".
