Excellent explanation.<p>I just came back and looked at this thread. This is the only answer I&#x27;ve heard that satisfies both &quot;here&#x27;s what we know,&quot; and &quot;here&#x27;s what we don&#x27;t,&quot; topped with a great mathematical analogy.<p>Your delivery was also welcome. Intelligent without being facetious, and elegant without being arrogant. Often it can be difficult for me to hear the merit of others&#x27; positions over the emotional noise.<p>Very sincerely, thank you.<p>If you don&#x27;t mind, this is the answer I&#x27;ll be using for a while.
