Second, it looks to me as though you are not including the mass of the moon as part of the mass of the Earth, thus the Earth and Jupiter do not round off to 100%. I suggest that for this system to work well, that a planet's dominance should be counted including itself and all of its moons, moonlets, and rings. This will prevent some rare system around another star where an orbit is occupied by two large co-orbiting bodies from having no dominant body in the orbit.


I have considered that in the past, but it seems unnecessary at the current time. For obvious planet-moon systems, only the "collision" genesis for moon's seems to create a moon relatively large enough to affect the percentage. Earth and Pluto, of course, are the only examples we have so that's a small sample size.

With regards to large, co-orbiting planetoids, I would defer addressing that possibility until the need arises. One important consideration, I think, it is always remember to not make decisions that are more appropriate for the future. If and when co-orbiting planetoids are discovered, we can then address that issue based on the observed data.
