I used Seraphi's lifetime just because it seemed like a reasonable benchmark; it doesn't matter that much because the math is... if you add another 10 billion galaxies, and another 10 billion years, you've still only got 10^40 humans to work with; but if you take it up to 1000 points of variability, you're at 10^300 odds of a recurrence - and humans very likely have millions of points of variability, at which point you're looking at trillions of universes, and billions more universes just to hold the computers that do the gene-matching.

So. IDK.

And if Entitled usually own at least one heavily inhabited planet (which seems likely?) you're looking at .000000001% or thereabout....
