Sorry if these have been answered before, but a quick search of the forums came up with a whole lot of threads about Knowledge Pool/Scribe Spell threads, and I didn't want to sift through them to find what I want.
At 7th level, a Magus gets the Knowledge Pool ability:
Knowledge Pool (Su)
At 7th level, when a magus prepares his magus spells, he can decide to expend 1 or more points from his arcane pool, up to his Intelligence bonus. For each point he expends, he can treat any one spell from the magus spell list as if it were in his spellbook and can prepare that spell as normal that day. If he does not cast spells prepared in this way before the next time he prepares spells, he loses those spells. He can also cast spells added in this way using his spell recall ability, but only until he prepares spells again.
QUESTION ONE:
"For each point he expends, he can treat any one spell from the magus spell list as if it were in his spellbook and can prepare that spell as normal that day."I read this as saying I can spend 1 point from my arcane pool to "add" Shocking Grasp to my list. Then I can prepare every single one of my 1st level spell-slots with Shocking Grasp, all my 2nd level slots with Intensified Shocking Grasp etc etc.... all for 1 arcane pool point.
Is this Correct? or would it be 1 arcane pool point per spell-slot?
QUESTION TWO:
If a Magus loses their spellbook, can they use this ability to prepare at least some spells that day anyway:
Eg. a 7th Level Magus with 16 Intelligence can prepare 3 spells using Knowledge pool without having their spellbook on them.
There are 2 ways I thought of interpreting this:
1. The spells are added to the spellbook, but since (s)he doesn't have the spellbook, it doesn't help at all, or...
2. The Magus designates a random book/scrap-of-parchment/wall/their own hand/etc as their (empty) spellbook for the day. Then with Knowledge Pool they add 3 spells and prepare them in some(all?) of their spell slots for the day.
Which seems right?
QUESTION THREE:
(Edit: This question assumes Option 2 from Question Two. If that's incorrect you can pretty much ignore this question.)
Let's say our 7th level Magus has Shocking Grasp as their Preferred Spell. Their spellbook has been stolen, and they've used Knowledge pool to prepare Colour Spray, Blur & Fly (random 1st, 2nd & 3rd level spell examples). Can they still use Preferred Spell to spontaneously switch out to Shocking Grasp? Or do they lose that ability since it's not in their current spellbook? (I'm expecting this one to be a "No you can't do that", but I thought I'd ask anyway).
(PS. I used Shocking Grasp in my examples because let's face it, that's what it's going to be used for 99% of the time)
1) Yes. You treat that spell as one you can prepare normally. Normally you can prepare a spell in as many slots as you wish, so you can do so with a spell from Knowledge Pool.
2) You can prepare the spells as normal for the day. This lets you prepare them even without a spellbook. Additionally, if you acquire a new, blank spellbook, you can copy the spells you have prepared into it. So you could acquire new spells using Knowledge Pool and get them into your book for cost of scribing only.
3) Yes. You know the spell so well you do not have to prepare it.

1) Awesome, that's what I thought.
2) I know there was a big debate about writing Knowledge-Pooled-Spells into your spellbook, but I've never cared enough to actually read to the end and see what the consensus was. If there was an official ruling there a link would be great. If there hasn't been an official ruling, anyone from the other side of the fence want to weigh in on this one? (just to have all my bases covered).
3) Sounds good. I just wanted to check because the description of Preferred Spell says: "Choose one spell which you have the ability to cast." I just thought I'd check if people think you lose "the ability to cast" that spell if you lose your spellbook.
There is no FAQ saying he can't, and given the plain language of both the section of the CRB regarding recording memorized spells into a spellbook, and the language allowing you to prepare a spell from knowledge pool, an errata would be needed to prevent it, I'm pretty sure.
