I'd call it course and speed made good..

Dave , you definitely will get 2 Anicula-points for your answer. And I

Oh yes, but I'm still a bit dazed by the question... it seems to me that
going around 4 sides of a large square is not really within the bounds
of VMG... usually 2 sides of a triangle are about the limit.

I was also suprised that nobody caught on to the diff in distance at
diff lattitudes... that was the first thing I thought of and was
surprised that it was not the point of the question.


I suggested "Velocity over the ground ..." which I think is the same,
(I assume that velocity has both a direction and a size). I am not
really that familiar with your language, but I think that "course and
speed made good" sounds simple and on the point.

Sure. Usually course made good and speed made good are two different &
seperate scalar entities. Velocity made good encompasses (pardon the
pun) both. VMG is usually thought of as the resultant speed toward an
upwind destination when tacking, or a downwind destination when reaching
back & forth; but it can just as easily apply any time you are not
heading directly toward your goal.
