I'm far more interested in what ya'all think, not what the rule books say. I own the books. Of course, if your opinion is that a specific rule in print is how it should be done, I would find that interesting to read also.
So, is the level of a spell equal to the total power points put into it? If I required power points to fuel each Spell Mastery pick, say 2pp, and the level 9 spell will have +5% added times to increase the total hits lost to 40%, the spell would then cost 15pp. Is this a 9yhlevel attack costing 15pp or a 15th level attack requiring appropriate prep/casting requirements for a 15th level spell?
