No drama, FWiW I'm familiar with the history of the phrase from Middle English, through Chaucer, Spenser, and Walter Scott .. and I'd suggest "misprint in the 16th Century" is a bit simplistic as language in that region in those times had an exuberance of spellynges until Samuel Johnson took a stab at nailing jelly to the wall.
I toss a mental coin any time I come to type such a phrase and note that we still translate the progenitor "dorryng do" as 'daring to do' and have derring-do littered throughout every volume of Ripping Yarns so it seems passable to spilt the difference. :-)
Apparently the technically correct spelling is "derring" because of a 16th century misprint.
Perhaps being technically correct is not the "best kind of correct" this time.
