Kanzenshuu

There was a point where I was reading the Viz translation and started piecing it together that maybe the "x2, x3, etc." referred to the Kaio-ken itself, not Goku's power
If the SSJ is a x10, then this is the only possibility. But

No,
Kaioken allows an amplification of the Ki . Then, with the chance (control of this Ki), allows to multiply the combat force.
Goku distinguishes the Ki and what makes up the fighting force. The amplification of the Ki and its control allow, with luck, to multiply the combat force (or combat power ...

In my opinion, there were not really any specific multipliers when he drew the manga. A boost just makes it a little stronger than the previous boost (Kaioken x3, x10, SSJ2, SSJ3). Only power up.
BUT
If there were, it would look like this :

The effects of the Kaioken are simply degressive.
The more power is amplified the more it is heavy and hard to control.
For example,
Kaioken x2 => Goku base x2
Kaioken x3 => Goku base x2,8
Kaioken x10 => Goku base x4
Kaioken x20 => Goku base x5

Then for Toriyama, ´Goku SSJ = Goku base x10.

The ...

The power of Kaioken is degressive.
Kaio said that the power of the Kaioken beyond Kaioken x2 is too heavy for the body.
In others words, Kaioken x2 amplifies Ki by 2 and multiplies by 2 the battle force. Kaioken x3 amplifies Ki by 3 but multiplies the battle force by a bit less than 3 ...

With kanzenban's translation.

The Power of the (régular) Kaioken is a x1,5 or +50%.
Kaioken x2 multiplies this power (on the regular Kaioken) by 2. So this is a x2 or +100%.
Kaioken x10 multiplies this power by 10 ...

Daizenshuu (and other SEG) are official, ok. But they aren't canon (as Toriyama).

I think Goku was at 8400.
So,
Goku base 8400 (over 8000)
Goku kaioken (x1) : 12600 (+50%)
Goku kaioken (x2) : 16800 (+100%)
Goku kaioken (x3) : 21000 (+150%)

Hi everyone !
I am one of those who think that the kaioken (x1) does exist.
I'm french so excuse me for my expression.

2 years ago, I thought too that "kaioken = kaioken x2", like the most of people. But when I saw the Toriyama's interview, I began to change my opinion.

First of all, there is a ...
