But there's no need to handicap ourselves, trying to make another OU Pokemon with lower than normal BST. There's no tactical advantage to lower BST than higher. Imagine if Breloom was BST 500. Just put those 40 extra stats into SpA. Doesn't change him too much, but makes him heavier BST-wise. Easier enough to just distribute the stats and keep 500 or 510 as the lowest BST.
