I'll be interested in the answer. For me it has always been a handy memory device to differentiate between deviation and variation. I know the "d" word used in bushwhacking is the same as the "v" word for mariners. The casual bushwhacker has no equivalent of deviation that I am aware of--although I bet that is about to change.Along the same "confuse-a-cat" lines, why do triangular-shaped markers (3 sides) use even numbers, while square markers (4 sides) use odd numbers?
