Glass Cannon vs Force Weapon vs Spark Flint

Wizard
Can someone help figure out the math behind this?
I want to understand if Force Weapon is really that superior, or if some number is misleading.

Lvl 60 wizard (fresh, don't make fun of my gear!)

1403 Intelect
Base DPS: 9467

Sparkflint only ( 12% ): 10690
Glass Cannon only ( 15% ): 10888
Force Weapon only ( supposed to be "15%" too): 12520

Glass Cannon + Sparkflint: 12122
Glass Cannon + Force Weapon: 14153
Glass Cannon + Sparkflint + Force Weapon: 15586

If anyone does, I am sure we can point out mutliple flaws in their logic. Hell -> Inferno your DPS almost doubles in the first act.

Doing math.
I heard the 15% on force weapon's tooltip is supposed to be 25%
They're multiplicative.
Magic weapon is bugged and giving twice the bonus effect, that's really all there is to it.
Yeah seems to add up:

9467 * 1.15 * 1.15 = 12520

Now the question is, is it really giving that much bonus? or is it a tooltip issue?
TEST 1:
Base damage no gear: 7.35
Short bow: 6.3 damage.
Base Damage with bow: 18.53

Glass Cannon DPS: 21.31 (15% increase = 21.3095) = 2.78 damage increase
Magic Weapon DPS: 24.51 (15% increase = 21.3095) = 5.98 damage increase
Familiar (sparkflint): 20.76 (12% increase = 20.7536) = 2.23 damage increase

Theory: Magic weapon is a 32.27% increase in damage.

So if we take theoretical 10.99 damage increase (totals from the increases above) we should have 29.52 DPS with all buffs up, but instead I landed at 30.26 (2.5% gain)

TEST 2:
Base damage no gear: 7.35
Hand Axe: 4.5 damage.
Base Damage with axe: 13.38

Glass Cannon DPS: 15.39 (15% increase = 15.387) = 2.01 damage increase
Magic Weapon DPS: 17.70 (15% increase = 15.387) = 4.32 damage increase
Familiar (sparkflint): 14.99 (12% increase = 14.9856) = 1.61 damage increase

Totals: 7.94 damage increase in theory, landing at 21.32 damage, in practice it gave me 21.86 a 2.5% gain.

Conclusion: Magic weapon is actually, a ~32.27% increase in damage.

**EDIT**: Math is fun.
There you go math done. Seems like stacked up they do have a multiplicative gain to them of a whopping 2.5%!
Same type of bonus - they get added together ...(15% +10/5%+ 12%) (ignoring the actual damage the familiar does here) ...

The MW damage bonus is DMG * 1.15 * 1.15 but I have seen a few threads that said extensive testing has been done with magic weapon and it is CONFIRMED to be a tooltip issue. It actually only gives a 15% bonus as it should.
