As for "DR" .... define it and use it any way you want, but don't try
and tell me *how* it should be defined and/or used or can be used, as
you don't have the training, experience, knowledge, background,
etc.,etc., to do so.

no master mariner -- as you proclaim yourself to be -- confuses DR with
pilotage. It is the same as claiming to be a 1,000,000 mile trucker and
confuse a two-speed axel with an overdrive transmission.
