agreed! the distance correlations with DMS only apply along the axis of the earth in those directions so it really doesn't correlate to much physically most of the time. even radians would make more sense to me, or more easily used degrees with a decimal fraction. it certainly makes math much easier, and calculators are not always convenient, and it's nice to have some quick idea in your head most of the time even when they are available. this is an example of inertia in a notational system rather than something that was logically considered i suspect. but few manufacturers want to buck convention even when it does make sense. it would be nice to have a choice of units.
