A phrasing I think would be accurate:
If Weapons + Armor is > 10 (not merely equal to 10), your organism is suboptimal.
There are two different things you could do to such an organism that would be strict improvements:
You could remove 1 Armor, saving size at no cost.
You could remove 4 Armor and add 3 Weapons, improving your predatory ability at zero net size cost.
