The best the verse has for this are vague long-distance travel statements that don't even support the multiplier numbers to begin with, and those got caveats anyway. Cell is vague and lifespan-based and more. Buu has teleportation, absorption, immortality, unknown timeframe, and the Bibidi ship issue. Beerus is legit af but doesn't backscale to Z. Piccolo's spaceship feat is far below what the multipliers say it should be.
Beyond that, you maybe get a few low FTL feats at best.
And yet we're stacking multiplier after multiplier after multiplier until we get these absurd values. For what? It sure can't be accuracy, the values being produced are not only not implied by the source material, they're actively fought or contradicted by a lot of the actual showings.
And this applies to basically every continuity besides Toei.
Manga?
Basically nothing. Maybe you can worm out a low FTL feat here or there, but the manga absolutely doesn't support the insane multiplier speed chain.
Kai?
A bit less egregious. You can definitely make a case for MFTL or maybe MFTL+ depending on what you use, but it's still excessive by the end. Even there, the multiplier chain is inflated by tens of thousands of times at best.
Toei?
Toei's mostly fine. They actually have some stuff to bridge the gaps. If any version has the least awful case here, it's Toei.
Super manga?
It's basically the manga problem again, except now Piccolo and Jiren get some MFTL stuff. But even then, those feats are still a few quadrillion times below what the multiplier chain says they should be. So it's the same issue: some feats are real, but they don't actually support the multiplier inflation. Stick to the feats, and only use the most explicit instant/transmission-type stuff where it's actually relevant, like be fr now.
Super anime?
Unironically, this might be the worst offender in the history of the site, Invisible Dragon fears what they may become.
And that's ironic too, given DBS anime actually has some absurd as hell feats. The problem is that even absurd feats still get exploited.
Take Beerus' energy ball feat. That feat is extremely high, bonkers even. It's one of the best feats that scales to a lot of the cast. But even that feat gets completely dwarfed once multipliers get stacked on top of it.
