Focus Spells and Focus Points

Attempt to give a solution to this problem where some focus spells indicate you add 1 to your focus pool and some do not. It is reasonable to conclude that a feat only gives you what it says it gives you and nothing else. However, there are some rules on page 445 about...rules. (Metarules I guess they would be.) Anyways, they indicate there are general rules that are in place until they are overridden by a more specific rule. That leads me to believe, then, that focus points are like this, and the "general rules" for focus points are pretty clear: Focus Spells, all of them, give you a focus point.
