It is consistent at present. If you are below final glide, then the negative number shows you how much height you need to gain before you can pure glide. In the case of Mc=0 in a headwind, that number is smaller than Mc>0, because the height you have to magically gain at Mc=0 is done instantly, for Mc>0, you are drifting downwind while you climb.
It is essential to take wind into account when circling!
