I went searching for more info in dave's blog (which he announced he was going to stop writing in) and found these references to his criterium specific designs:
"If I raised the bottom bracket on a criterium frame, it was not just to achieve more ground clearance; it was to make a more rigid and responsive frame. The head tube became longer, but as this is the least stressed tube in a frame, it had little affect. On the other hand, the down tube and chainstays are the highest stressed tubes in a frame and shortening these is a definite advantage."
"....one of the custom models I built called a "Criterium" frame. It had slightly steeper angles and was designed to be ridden fast and hard, and handle quickly. "
"A fork blade is several inches longer than it needs to be. The framebuilder chooses where he will put the bend, and where he will cut to length. For example, if I were making a criterium frame and wanted a very stiff fork, I would cut from the bottom, thin end."

dave moulton built 36 "special Professional Criterium" bikes. If you look in the archives you can find the differences between this and his road bikes; my recollection is a higher BB, used a track tubeset (Columbus PS) and he used round fork blades, I'm pretty sure there was also a difference in the frame angles.
