50x comes from the fight in Episode 109 looking like Goku vs Freeza on Namek: Goku first tries Kaio-Ken, then a Genki-Dama, then a new form. 2.5x for UI is just an educated guess, but that's a nice catch on Jiren being somewhat over 2x Sign Kamehameha. I just think Jiren isn't absurdly stronger since he was probably close to FP against Goku, Vegeta and 17 since he was so pissed off but wasn't strong enough to beat them instantly.
Hmm... So, you believe that in this way, it parallels the Freeza Saga & the Super Saiyan form? Interesting. I have heard that people put the ToP Genkidama at 40x Blue (because it was withstanding the impact from two fighters at 20x Blue tier or more), so a 50x multiplier would fit. Reminds me of the Kaiouken x20 Kamehameha being a fail too, with that being roughly 40x Goku, then with SSJ of course being 50x.
As for me (in the anime), Jiren tanked a Final-Kamehameha from Goku & Vegeta in their 20x Blue forms, so (20x2.22)+(20x2.22) = 88.8, Jiren tanked that & UI -Sign- contended with him, if I remember rightly. Although, I have the Final-Flash at more than 2.22, but that's more speculative regarding P. Cell & Grade 3 Trunks' 500x multiplier.
SSJBE does better than Blue Kaio-Ken, so I think the latter was more like 10x. The strain might have messed up Goku's effective power though, so whatever. Jiren even says Goku is messing up his body.
True. Though I could've sworn it was stated in an interview that Evolution was superior to 20x Blue to some extent. Can't find it though.
That's actually a great catch, although some people could argue Piccolo can just guess if he knows Base Gogeta and knows SSJB's multiplier.
Yeah, I think Piccolo could make an educated guess since he's seen the difference between Goku/Vegeta & Gogeta in the Broly movie, & has at least sensed his base & SSJ forms.
In the novelisation of the movie, he states that Gogeta's base has greater ki than initial SSJ Broly, who he knows to be superior to Blue Goku/Vegeta,
so I think he could make a ballpark estimate of Blue's multiplier.
He also sensed Ikari Broly (no God Ki), who was roughly equal, if a smidge weaker than Blue Goku.
It's all academic though, since Piccolo likely only made the Moro/fusion comparison because of Forced Spirit Fission.
Either way, it's not a very smart statement since Gogeta also has Spirit Fission and might even have UI Sign, so Piccolo was just being pessimistic here.
Indeed, considering the possibility of Gogeta having UI -Sign-, I don't doubt that he can blitz Moro the same way that Goku dodged his draining magic. He also benefits from FSF, he can fissure his energy, & also remove 73 from Moro. So it would come down to who hits who first.
