I do not see where you are going with this.

I'll explain. But you've already answered my question, Travis.

All I wanted was the bottom-line source of your estimate. Now you've explained that it comes from a source that you consider trustworthy but who offers nothing substantial (Ford documents, citations from another's published work, etc.) in support of his claim. That's all I want to know. And I think its all anyone else would need to know, as well.

I'm perfectly happy taking sources at their word, for what that's worth. But I think most of us are hoping they'll have something more substantial to back them up. Otherwise, their claims will be suspect if contradicted by a seemingly more credible source. After all, if the true figure was published by Ford then one either has  seen it or not....its as simple as that.

Anyway, thanks for clearing it up. I appreciate your directness.
