Magic Item Crafting Bonus Stacking

[Haskalah]

Alright, currently one of the quickest crafting methods I've found works thus:

Dwarven Wizard w/ the following:

Valet Familiar
High enough Spellcraft to take +5 on his DCs
Favored Class Bonus as a Wizard
Arcane Builder (Wondrous Items)
Craft Wondrous Item Feat

The question is.. How do they stack?

Is it (1000 + 200 (Dwarven Favored Class)) * 2 (+5 DC) * 2 (Valet Familiar) * 1.25 (Arcane Builder) or is the Dwarven Favored Class bonus added in at some other point?

The thought is that the Dwarven Favored appears to add +200 to the amount you can craft in a day IE onto the 1000 initially, making it 1200. The +5 DC appears to work by allowing that amount to be crafted in 4 hours. Is this accurate?

Well, right off the bat, two multipliers go to a triple in PF rules. So Valet + speeding up the crafting is an x3.

How that interacts with Arcane Builder or Dwarf is anybody's guess.

I know that this is true for critical and other damage multipliers, but is it also true for item crafting?

I hope not, since it's already hard to speed this up!

Multiplying: When you are asked to apply more than one multiplier to a roll, the multipliers are not multiplied by one another. Instead, you combine them into a single multiplier, with each extra multiple adding 1 less than its value to the first multiple. For example, if you are asked to apply a ×2 multiplier twice, the result would be ×3, not ×4.

It's true for everything

EDIT: (1200)*(2 [valet]+.25[arcane builder]). You can work for 8 hours a day in uninterrupted 4 hour blocks, so you can make 2 such checks a day if you add +5 to the DC to craft that amount in 4 hours.
I've added Arcane Builder where I have as it will reduce the time to craft the item that way, but technically it could be argued that Arcane Builder reduces the time to 6 or 3 hours, but that is actually of no real benefit.

They do not multiply the same thing. Valet Familiar doubles the amount of gp worth of item crafted while the +5 DC doubles the speed of crafting.

Valet Familiar (Cooperative Crafting) doubles the amount of gp you create each day, lifting the regular 1000gp to 2000gp for 8 hours work (remember, you can not spend more than 8 hours to craft each day). While the +5 DC halves the time it takes to craft. It takes 4 hours for 1000gp instead of 8 hours, meaning you can spend another 4 hours crafting another 1000gp that day.
So together, you can craft items at four times the rate, 2000gp each 4 hours making for a 4000gp in total each day (8 hours of work).

Valet Familiar
base value x2

High enough Spellcraft to take +5 on his DCs
change time intervals to 4 hours

Favored Class Bonus as a Wizard
+200 gp x 8 hours or for time increment. Apparently a fixed value. (the bonus is written really badly. Nowhere it say that it don't stack. It is not a time increment, it is 8 hours, so working at double rate isn't affected?)

Arcane Builder (Wondrous Items)
"You create items of this type 25% faster than normal,"
8 hours of work count as 10? Another badly written piece of text.
Let's suppose that it mean you produce 125% of the base value.

So Base value 1000x2 (valet familiar)+1000x.25 +200 (dwarf wizard)
2450 with each time increment.

Now the spellcraft check allow you to reduce the time increment to 4 hours.

You are capable to do 4900 gp of work for magic item construction in 1 day, but you can still craft only 1 magic item in a day.

The problem is with the Favored Class Bonus. Typically, applying no other bonuses, you can craft 1000 GP in one 8-hour day. I feel the favored class bonus should apply at this point because it's before any other time modifiers such as how much extra can be crafted or how much can be accomplished in half the time.

It's really about defining what a day of crafting is. That appears to normally be 8 hours of crafting. By that reasoning, if we can accomplish 8 hours of crafting in 4, I believe the Favored Class Bonus would apply to that 4-hour period (since DC +5 allows you to basically craft a day's worth in half the time).

The rest of the modifiers (Valet and Builder) I also believe should go together because they affect crafting separately, Builder allowing more crafting and Valet doubling your final output.

I also apologize with side-tracking the conversation with multipliers. Each of the modifiers works independently because they affect different aspects of crafting.
