I agree, and would go further and say that we don't even have reliable enough models to relate such data to. Astronomy is in the infancy of understanding and observing planet formation. We only know some of the large factors that come into play. If you're writing speculative fiction, and need something plausible, go for it. No problem from this end. If you're stating something as though it is a result of deductive reasoning, you've gone too far.
