Re: More than a coincidence?
It has been suggested that Bodes Law arises because of orbital resonances between planets in relatively circular orbits but even in our solar system it fails once you get to Neptune. We already know of solar systems containing large planets in very eccentric orbits which would presumably disrupt any Bodes Law pattern in their system. Hence it seems a bit of a stretch to attempt to calculate the average number of planets in the habital zone using such a law.
