@Clacker: In the reach battle you start with 20,000 battle points and you gain or lose points depending on score above or below 30,000 points. If I remember correctly, the uma spread is (+200/+100/-100/-200), but that is off the top of my head and I'd have to check to confirm. Also, there is a ranking system level scale where you gain or lose levels depending on your placement. In D5, where you start, taking 1st will give you 2 levels, 2nd will give 1, 3 is no change and 4th is -1 level. I have no idea what happens if you completely run out of points, as I haven't had that happen yet. But as a side note, the biggest point change I've seen so far is a 500 point swing in either direction for a tonba/hanchan.
