Otherwise there will not be any reason to think that the multiplier works differently, the official statement is clearly saying that it is "A x B" without any indication of any sort of thing being different as far as I could see.

The Super Exciting Guide (SEG) was released in 2009 by Shueisha. There were several writers that contributed and not all of it was supervised by Akira Toriyama. No matter what mathematical power scale you use, multiplication will never give you a logical result. In DBS, Episode 114, Vados literally states that "more than the sum of their parts and their power increases tens of times". DBS is much more recent and supersedes any information contained in a databook 9 years ago. Translating Vados' words into a formula, you get (A+B)x C where C is "tens" of times. However, using math again, in order for Base Vegito > SSJ3 Goku,

(A+B)xC >400 x base -->

(base+base) x C > 400 x base -->

2*base x C > 400 x base -->

C > 200.

Hence in order to satisfy that Base Vegito > SSJ3 Goku, C>200. This is "hundreds" of times stronger than the sum of the individual parts, which is more than "tens" of times.

We are all waiting for the manga to clear up Kefla and see if Vados says the same thing or if she will say something different. If Potara is confirmed to be truly multiplication of the individual parts, then multipliers for SSG would sky rocket.

It does "prove" that it is 10x, it "proves" that SSJ4 Gogeta is "tens" of times stronger than SSJ4 Goku which means anywhere from 10-90. Dozens of times means 12-96. That is in the formula, (A+B)xC, C =10 - 90 and this depends on many factors like whether the fusion dance was done properly, the physical characteristics of the fusees and how similar they are. In my sig, you can read the details under "log power scale", but the point is that we don't know exactly, we only know a range. 90 is the max. By logic, SSJ4 cannot be more than 100x a Golden Oozaru because that would be greater than fusion, so SSJ4=10x Golden Oozaru is a reasonable guess, which means 5000x base.
