Goku didn't absorb the god power
I'm tired of all that anime "absorbing god ki into the base form" nonsense.
First of all, character statements can literally be wrong, like, we were told that the ginyu force dude is the fastest being in the universe.
But second of all, I don't believe the statement is wrong per see. instead, I think it should be understood differently. to explain my understanding of this topic I'll first mention something. No character ever enters the pink haired SSG form in the anime post BoG. Why? This form was simply them using god ki in base, and SSB is them using SSJ on top of SSG, so it makes sense for them to be able to access SSG before SSB in the anime.
The answer is they do access it, but simply without the pink-haired form, as in the anime this form only symbolised that the divine qi was channeled through goku's body forcefully.
When they're fighting using god ki in the anime, it's no different visually from simply staying in base, but they have to manually tap into it.
So the power levels go as follows:
Base goku = ~billions
SSJ 1-4 goku = 50 to 400x base (up to a trillion or smth)
God ki base goku = ~quadrillions
God ki SSJ 1-4 goku = ~quadrillions, as only the base power level gets multiplied.
SSB = 50x god ki base (hundreds of quadrillions, but at the moment when they unlock it their base has already increased to like tens of billions so it turns into quintillions, just enough to match 10 quintillion golden frieza)
It's perfectly consistent and it explains why tournament of power cannon fodder made saiyans tap into super saiyan almost immediately, their power lvl was in the trillions. Not even remotely enough to rival gods, but surely enough to overpower base goku WITHOUT god ki.
