Incidentally, I had always heard 4%MC quoted as the preferred dry down 
level for this type of construction. When did it become 4.5%, and why?

     I don't know & ...I don't know but I thought I just read on this list 
recently that John Patton Of S&S is now stating that their boards are now being 
pressed at 5.5% EMC. To me this would yield a fairly amount of crown in the 
rehydrated panel. To achieve this level for sure takes a well set up box & 
regular monitoring.
