I copy/pasted this statement directly from that link you posted: "I think what it boils down to is that my hasty assumption of uniform load sharing among multiple bearings is correct only in the case of a perfectly rigid shaft. Elastic flexure completely disqualifies this multiple bearing approach in reality. I really should have seen the impracticality of this approach earlier."
