Why was the Spirit Bomb so powerful?

[BWri]

I'm not entirely sure what kind of correlation Genki has with power, so it could be chalked up by just saying that everyone is a lot stronger than they were before, but honestly it's probably just bad writing. (Also notably, no plants or animals to draw power from are in sight either)

It would be less of an issue if many of the people from apposing universes, after seeing how strong Jiren is, decided to help lend energy because of seeing it as an easy way to get Jiren ringed out or something like that.

On a somewhat related note, it still annoys me that Vegeta refused to lend energy, especially since even Frieza of all people was willing to lend a hand.

It's tough for me to call it bad writing since Genki itself is such a vague concept, but I suppose I can as vagueness is often the sign that an idea isn't fully fleshed out. From what's presented in the show so far, the Spirit Bomb's power makes no sense, but perhaps (headcanon territory) Genki is stregthened as you get stronger or maybe god ki enhances it. IDK, I'm trying to throw them a bone.

I feel like the problem is that Z didn't raise the questions we have with this, so there was no need to answer them, but Super raises several questions with the spirit bomb's usage here, so they probably should have also gave some answers.

100% agree. I felt the same in the Goku Black arc as well with how Trunks used it and how effective it was.

Because it actually consisted of fighters’ energy for once.

Also, 17 and Frieza are incredibly powerful, and 17 and 18 both allowed Goku to take energy from them until he reached his limit.

Genki is also exponential.

[Miracles]

Any Genki Dama created is powerful but it varies.
Against Jiren and Vegeta, They didn't use the entirety of the planet and people.

I agree with this statement. I posted a long response on the previous thread about this using the dreaded "maths" to explain why this whole scenario was bad writing but this is really a much simpler and easier to understand reason.

The biggest question to me lies in how Genki scales in relation to the technique. Against Kid Buu, billions of people contributed to the bomb, including Gohan. This is important because Gohan alone was almost certainly stronger than Kid Buu (unless you're part of the minority that still believes Kid Buu was stronger than Super Buu). Despite this, it took his energy, the energy of the other Z-Fighters, and all of Earth to take on Kid Buu, and even then Goku had to be powered up in order to push back and overwhelm him. After forming the bomb, the people of Earth were exhausted, so Goku clearly drew a lot of energy out of them. In this instance, the scaling seemed quite lousy.

Contrast that with the latest bomb. Goku forms a bomb from 8 individuals: Freeza, Gohan, Piccolo, 17 and 18, Krillin, Tien and Roshi. The energy they give is voluntary and not enough to leave any of them even winded. In addition, none of them are even remotely close to Jiren's strength. Despite these shortcomings, the attack was treated as Goku's ultimate weapon, trumping even SSB with a Kaioken x20 multiplier. In this instance, the scaling seemed quite extraordinary.

So, why is the bomb scaled so much better in scenario 2 compared to scenario 1? How does Genki work, exactly? Does the bomb's power scale with the user, like some suggested? Were 17 and 18 able to contribute ridiculous amounts of energy in a short period of time? Is Genki exponential in nature, therefore making Freeza's contribution significantly higher? Has Goku improved the technique at some point between then and now? There are many questions, but there are no given answers.

That's why it's bad writing. Still looked cool, though.
