As per usual, a number of problems with this post.
1. It is in no way a response or related to my post.
2. You are wrong when you say "DR" is never dead on (but that's beyond
your knowledge or experience).
3. I didn't see anywhere, where Jeff introduced "pilotage" in a way to
change the definition.

Sheesh, you do ramble.

even guessing for wind and current makes no difference.

now, over the knee, *if* you -- like jeffies before you -- wish to change the
definition to the term to include pilotage, well go ahead. At least you would
be safer should you ever find yourself on the water.


over the knee obviously does not, so let's help out a bit.

You gotta make up your mind, jax. You were talking about "dead
reckoning" before, the term many use when employing time/direction/speed
only.
"deduced reckoning" applies when allowance is made for wind and current
.... something you say is impossible.
Mayhaps you should go back to the books for some further study.
