This is exactly the theoretical basis of the calculation I used in my OP.
I am very prepared to concede that I'm not entirely across the rationale for the seemingly simplistic nature of this calculation (and I have been challenged on it elsewhere), so I've been on the 'hunt' since my OP. Here's some Wiki words confirming what's in the Horizon doco (for those wondering about the calculation). Love Max Tegmark's presentation style, by the way. (Also cracked up at the 'interview' room, which was crammed packed full of so many papers that the creepy interviewees, barely had room to fit in !  )
Whilst its a very high level approximation, there's a lot underlying the seeming simplicity of the calculation. Tegmark's original paper on Parallel Universes explains the details (and there's a lot of them).
I'll have to catch up on the Nova presentation, shortly .. I haven't seen this one yet.
Many thanks for the links … you're really collecting a great library of good docos ! .. Very much appreciated.

Hi Craig,
I had a quick look at Tegmark's paper.
Unfortunately I couldn't find the mathematical derivation behind this calculation, so I'm cynical.
