Jeff's guess is better than mine. I would dispute his assertion of no evidence. Understandable, for an engineer, who prefers facts over mere 'evidence.' But evidence he has nonetheless, and he knows how to use it.
Gosh it had to be frustrating, Jeff, to work for that large, inefficient, impersonal company. Based on my observations from a distance, that company almost could not have been managed more poorly. You should have developed a drinking problem by now.
