No doubt about it, as long as these methodoligies are accurate and repeatable.

Exactly; and if there were evidence that these methodologies were erroneous, you'd have posted it by now.

Lacking any evidence that they are erroneous, we conclude this is the best estimate we have, and our confidence in it is much greater than before we had this independent methodology that produces virtually the same answer.
