I saved his argument/post:
People say "SSG appeared in the ToP arc, there before base Goku isn't SSG level"
Akira Toriyama degrees with that statement her is why:
Battle Of God's Movie Interview
English translation of Akira Toriyama's Q&A session from the 'Anime Film Comic' version of the film 'Dragon Ball Z: Battle of Gods'
www.kanzenshuu.com
[Will Goku be able to transform into [Super Saiyan] God in the future?]
"I think you’ll understand if you watch [the movie], but Goku has already absorbed [Super Saiyan] God’s power and made it his own, so there is no need for him to transform into [Super Saiyan] God. Goku basically only thinks of fighting as a sporting match, so borrowing the power of five people isn’t fair, and he resisted doing that; however, it seems his curiosity towards the realm that lay even further beyond him won out."
So according to Akira Toriyama even though Goku absorbed SSG in his body, he can still go SSG, but doesn't need to(His logic, not mine)
Also in the BoG movie when Goku runs out of SSG and tries to stop Beerus's Sphere of Destruction attack in his SSJ form
Beerus comments: "You have absorbed the power of SSG in your body, your haven't powered down that much at all"
And later on Goku goes SSG again to stop Beerus's attack after he already absorbed it's power in SSJ form.
So according to Beerus, SSJ Goku is relative to SSG power and later on he can stack SSG on top of that.
So BoG Movie scaling is like this:
Post-Absorption SSG>Pre-Absorption SSG>Post-Absorption SSJ Goku
Also this directly parallels the BoG anime as follows:
BoG Movie: Goku loses SSG and aborbs it and his SSJ form becomes not that much weaker than SSG
BoG Anime: Goku loses SSG and absorbs it and his SSJ form surpasses SSG
BoG Movie: SSJ Goku fails to stop Beerus's attack and revers to base form
BoG Anime: SSJ Goku fails to stop Beerus's attack and reverts to base form
BoG Movie: Goku goes SSG to stop Beerus's attack and succeeds
BoG Anime: Goku stays in base and breaks his limits to stop Beerus's attack and succeeds
As you can see in the BoG movie it's SSG transformation that stops Beerus's attack, but it in the anime it's base Goku. Showing anime base=SSG parallelism.
I can say much more, but this should debunk it.
