To send us off on another tangent, and one that I haven't seen mentioned
in this thread before, it's "ded-reckoning", not "dead-reckoning".

Baloney. Please see Google for the vast discussion on that particular topic
right here in this newsgroup.

Ignoring the fact that "deduced reckoning" is a perfectly redundant phrase,
there is ample evidence that "ded reckoning" is elitist after-the-fact
revisionist history-making, and that it's been "dead reckoning" all along.

If and when you have incontrovertible evidence that the correct deriviation
is "deduced reckoning", feel free to make such a correction. Until then,
you're just creating unjustified smugness for yourself.
