To be fair, this is why i said the "Rules of Narrative" are important. Plus, even in DB, Power Levels have always been iffy. I mean, 17 was able to spar with SSGod Gokua without much problem. And considering that he wasn't strong enough to deal with Imperfect Cell and, without any clear visuals of him getting stronger somehow, managed to also go toe-to-toe with Jiren, i think it's clear that they bullshitted some numbers.

If Character X has to lose to Character Y in order to suit the narrative and make everything fun for everyone, then Character X will lose to Character Y.
