The change log suggests the cost for a victory point is the formula:
7.5 + (round)*12.5 / 3000
Is that correct? Or is the 3000 the total number of rounds for this match (rc.getRoundLimit)? I ask because the spec also suggests that matches could be 1500-3000 rounds. I don't believe I've seen any matches that were limited to less than 3000 rounds though.
