Toyotaro usually does note if a character makes a major power-up, such as the case with Piccolo himself during the Moro by having Goku say he barely recognizes him. It's possible Roshi is a lot stronger, but if he was anywhere near Base Goku then something would have been said. Then again, I don't remember what Roshi accomplished in that tournament besides barely dodging Jiren a few times, so you'll have to help me out with that one.
I feel like RoF is either rewritten or simply not taken into account for the scaling in the actual Super manga.
I really don't believe that. The narration for the FnF arc said that Goku and Vegeta defeated Freeza together as SSJBs, but we saw in Freeza's flashback to the moment he was killed again on Earth that SSJB Galu just rushed in to wipe him out to prevent him from blowing up the Earth. That, and the artwork Toyotaro did of Shisami and Sorbet being the only ones next to Freeza, along with him retaining the movie's interpretation of sensing Godly ki (base form mortals can't do it, whether they have God forms in store or not) all points toward the manga arc being more or less the same as the movie imo.
Roshi has to be a lot stronger based on him dodging Magetta, managing to hold that robot eye Pride Trooper dude's arms in place and actually managing to damage him (whether or not his raw power was weaker) among other things. He'd just die from being exposed to other people's ki blasts if he were still on his 22nd level or less. This isn't the first time Toyotaro did this either, like when he made Kibito (who was weaker than base Gohan) keep up with Zamasu who Goku needed to go SSJG to stomp. It's possible present Zamasu is weaker than Future Zamasu, but to the extent that he'd require some effort to beat someone who was weaker than base Boo arc Gohan? I don't think so.
I think Toriyama went with base Goku and Vegeta making all of the side Z Senshi look like ants in FnF, but by U6 he figured he can't just make Goku and Vegeta the only relevant players a la the Evil Dragons arc of GT and decided to beef up other characters like Piccolo, Gohan and #17, whether he had to resort to contrived "explanations" (or even zero explanations) or not. #17 going from weaker than 1st form Cell to PSSJB tier from doing "not much of anything" may as well be zero explanation in of itself, but AT did it so he could make other characters relevant while Goku is away. Toriyama really honestly doesn't seem to care much for logic anymore. Gohan's case was just as egregious with him getting stronger than #17 just from "adapting" to Kefla and some of the other ToP fighters he clashed with. Whether that was Toyotaro's idea or not, AT still approved it.
