Ok, fixed Ultima and Mad Science. As Raven said, 2 Swords is not a bug, and happens in vanilla. No idea about Armor Break and Head Break, since all that was changed from vanilla was that it has CF flagged.
As for Cover Fire, patcher has it as what is listed in the master guide, while you have maintained that it's {1...X} * [PA + (PA + Y) / 2]. Try checking against your formula.
