Toriyama never cared about power levels and it makes no sense for Toriyama to suddenly scale Goku and Vegeta down after he made a big show of how powerful Goku's base form was in Reserrection 'F'.Cipher wrote: Toei was notorious for their lack of coordination early in the series (find Super's explanation for the Pilaf gang's youth). It's entirely possible they adapted the movie arcs without realizing Toriyama was writing the new material differently, leading to oddities in some of the filler episodes.
What really locked that reading in for me was Toyotaro's consistent approach that characters weren't substantially stronger outside of their god forms, and Trunks sparring more or less evenly with Goku's corresponding forms, while still being shocked by their godly power once he feels it. That also keeps Zamasu around an original-run Super Saiyan 2, which is still prodigal for a Kaioshin (remember, that level of power put the cast at the very top of the universe outside Beerus and Boo during the Boo arc), but not so strong that Beerus could have jumped over there for a challenge if he was truly impressed by Super Saiyan God.
Retroactively applying that approach to the Universe 6 arc -- the part of it Toriyama actually wrote -- makes more sense of it as well. I suspect the change was due to one or the other party between Toei and Toriyama wanting to have weaker forms available to Goku and Vegeta to add some visual flair, and the lack of consistency was due to Toei not getting the memo/really noticing Toriyama's changed approach. Which Toyotaro, as a single-author and super-fan, did, and adapted to.
Toyotaro is a none factor because he's telling his story of Toriyama's outline and he has changed more things from the movies Toriyama wrote compared to the anime. So I don't see how he's more in the right based on nothing but trying to guess what's in Toriyama's barebone outline.
And those breather episodes were written after the U6 tournament.
