The effectiveness of the dance was the key to Gotenks's strength

[kriss-]

They weren't paying attention to it. Only Dende and Piccolo were.

 

[Diamond Ryan]

After Piccolo told Krillin about the change in Boo's ki, Krillin still thought that Gotenks could win.

 

[kriss-]

Kuririn was placing emphasis on Goku's predication and not necessarily what he sensed from Super Boo. However, he doesn't notice a change in Majin Boo's superficial Chi because it is essentially the same as it was before, and his power-burst was temporary and not stationary.

 

[Tapion]

Anyone remembered that nobody was paying attention to Buu on the Kaioshin Realm and suddenly everyone sensed his ki due to how high it was?
So attention doesn't matter.

 

[kriss-]

The implications of Goku's statement suggest that he was sensing Boo all along from the Kaioshin realm.

 

[Diamond Ryan]

I know, but according to you isn't his superficial ki the same as Fat Boo's ki? And Krillin still though that Gotenks could win.

 

[Evil Vegeta]

If he did, then he wouldn't have wondered if the Chi belonged to Majin Boo. It just shows all of them looking off into a certain direction. Gohan was supposed to be focusing on the ritual, but Super Boo's power even got his attention.

 

[Tapion]

Actually, only Goku was paying attention on Buu's ki, everyone else was minding their own business or looking at Elder Kai. Even Gohan turns his head in shock a few images before Goku comments on Buu's ki.

Also, Goku doesn't even know who Pure Evil Buu is until Vegeta tells him like 30 chapters later. Goku wasn't paying much attention.

 

[kriss-]

I may have worded things incorrectly before-hand, I'm kind of tired.

Anyways, Krillen is placing emphasis on Goku's prediction and how Gotenks should definitely win no matter what, as opposed to the amount of Chi that he sensed from Gotenks.

There is no sure statement that Gotenks lived up to the expectations Goku had for him, and it is kind of illogical for someone to say that he had. Additionally, Super Boo's initial battle power - the battle power that he arrived on Korin's tower with, is implied to be the same as Innocent Boo's. Hence why Piccolo has to inform Krillen that Gotenks stands no chance, and he has to tell the boys that more then just his appearance has changed. Just because his battle power is the same as it was before doesn't necessarily mean that he is actually the same Boo from before.

Goku also noticed a change in Majin Boo's Chi, so it implied that he was sensing something all along. Even if you wish to disregard that, Goku was continuously sensing the events on Earth -and even at one time, he wished that he had some way of actually seeing these events; hence the introduction of Elder Kaioshins crystal ball. So it isn't surprising that he caught onto Super Boo's power-burst.

Everyone on Korin's tower except Piccolo and Dende were acting rather casual. Krillen was walking around without a care in the world, Goten and Trunks were sleeping, et cetera. It's no wonder they didn't catch on.

 

[Tapion]

But he didn't sense Pure Evil Buu even though he was there the whole time.
Also, he said:
"That's Buu's ki, is'nt it?"
Which implies that he wasn't paying much attention, because he didn't even know if the ki was Buu's. If he was paying attention, he would've said something like:
"I was observing Buu now..his new ki"

 

[Evil Vegeta]

Goku was only shown to be paying attention to Earth after the change to Super Boo, but he even missed all of the Earthlings being wiped out. No way was he keeping up with everything that was taking place.

 

[kriss-]

Yupers, and everything implies Super Boo's power-burst wasn't the same as his superficial power for reasons already stated.

 

[Tapion]

Which are easily disregarded by the fact that none of the characters that were actually relevant in that Arc said anything about Super Buu's ki going down.

 

[Evil Vegeta]

Looking back it, Super Boo showing off power akin to Fat Boo's doesn't make much sense. If it was just a matter of a power burst appearing and disappearing, why did a) Piccolo talk to Krillin about that change in his Chi as if it was already present, and b) why was Goku able to keep track of the same Super Boo's Chi the entire time? If he just allowed his power to unleash for an instant before suppressing it, none of that makes any sense.

 

[Diamond Ryan]

Didn't Goku note that he couldn't sense Boo's and Gotenks's chi after they went into the RoSaT?

This would imply that he could beforehand.

 

[Evil Vegeta]

He said Boo's Chi was gone, said that he doesn't feel the fused Chi of the kids, and wonders what happened to them.

We know he couldn't have been actively sensing Gotenks before Boo went into the rosat since he wasn't merged.

 

[Tapion]

The fact is that nobody but Goku was paying attention on Buu in the Kaioshin Realm, but they still managed to catch Buu's power up immediately. Even Kibito and Kaioshin are sweating to show it.

Which means that paying attention or not, Krillin should be able to catch the power up, and he didn't. Too bad. Krillin is a shitty ki sensor since C.G.

 

[Evil Vegeta]

Yeah, I don't see how Krillin's lack of a reaction really changes much.

The same Krillin straight-up looked at 3rd form Freeza and said he barely changed. He isn't infallible.

 

[kriss-]

Looking back it, Super Boo showing off power akin to Fat Boo's doesn't make much sense. If it was just a matter of a power burst appearing and disappearing, why did a) Piccolo talk to Krillin about that change in his Chi as if it was already present, and b) why was Goku able to keep track of the same Super Boo's Chi the entire time? If he just allowed his power to unleash for an instant before suppressing it, none of that makes any sense.

I think you missed the point.

Super Buu's initial battle power is what is akin to Fat Buu. His temporary power-burst is how Piccolo and Dende know that Gotenks doesn't stand a chance. But nobody else knows because everybody else was preoccupied with other things as opposed to acknowledging the events unfolding down on Earth. Hence why Piccolo has to explain to Krillen, Goten and Trunks that Buu has powered up because his superficial battle power doesn't appear to make the situation as hopeless as Piccolo is making it out to be.

Goku's statement implies that he was sensing Buu all along and he places emphasis on how Buu's Chi has taken on a different feeling as opposed to being a whole lot greater, but based on Piccolo's reaction, it is safe to say that it was.

 

[Evil Vegeta]

I don't see how I am.

Super Boo's initial power is his temporary power-burst. This was what got everyone's attention from a distance. The last time Goku was shown on the Kaioshin world, he was just chatting with Kaioshin about the Old Kaioshin. We're given no reason to assume he was sensing Boo or paying attention to anything that was taking place on Earth. Krillin simply wasn't noticing the change like Piccolo, Dende, Goku, Kaioshin, and the others were. That's why Piccolo asks Krillin if he could feel the change in Boo's Chi. If he suppressed his power, why would Piccolo even bother asking him? It was still there for anyone to sense.

The whole preoccupied stuff is kinda hard to use as evidence when Gohan was shown to be preoccupied with the ritual. Once the change to Super Boo happened, Gohan realized that he might not be finished in time to save the world. Goku's reaction seems more like he just sensed the transformation and wondered if it was actually Boo's Chi to me. Had he been sensing Boo all along, how did he not sense 2 different entities with Chi noticeably different from everyone else's? Vegeta had to tell him Boo split in 2 before the change into Super Boo.

Nothing implies he was sensing Boo the entire time. Even the anime doesn't.
