I think you're on to something, Jon.  I've been cutting my plates under
fluorescent lights, which I recently discovered significantly fog my pt/pd
prints in a matter of 1-2 minutes.  Since km73 is faster under UVBL than
pt/pd, I wouldn't be surprised if my plates have been "fogging" too.  That
may account for my utter lack of plate tone...  :)
