Thanks, Charlie. This clears up a lot of things. Such as:

This really breaks my heart. I'm so fond of the bugger factor library 
approach, so I don't have to understand applied mechanics. ;->

Damn fine. This approach makes much better use of fatigue test data than 
guessing an appropriate SCF for polished bar test results. (How about the 
term 'limit jungle' rather than 'limit state' referring to areas like 
fatigue where the criteria are a continuum?)
