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

God damnit, I typed up my response but my browser crashed.

Super Boo's initial battle power is what he started off as after Good Boo and Evil Boo merged into one being. His temporary power-burst -which can after this, is completely different from it. Goku, Kaioshin, Gohan, Dende and Piccolo all catch onto it, but nobody else does. Why? Well... Krillen already believes that Goku's prediction and that Gotenks will be superior to Majin Boo no matter what. Meanwhile, Goten and Trunks were sleeping so it's explainable as to why they did not notice it. Regardless, it does not take away from the fact that even when they are formally introduced to this new Majin Boo, they do not notice a significant difference between how he is now and how he was before-hand. Piccolo has to blatantly tell them that more than just his appearance has changed. What change? Chi is the only logical determination. Based upon all the evidence, his superficial battle power is the same as it was before-hand.

Because Krillin is ass at Chi-sensing for this duration of the story.

Piccolo: “Can’t you tell…?! As they are now, even if they perform Fusion they can’t win, no doubt about it…! Tell them that if they don’t want to die while they’re still just little brats, then they should train as much as they can…!”

Krillin and the kids simply aren't sensing the monstrous change in Boo's power like the others. Why? No idea. However, it's clear that Piccolo believes Krillin should've caught on to Super Boo>Gotenks by now.

Super Boo's burst got the Kaioshin world's attention. From then on, Goku could feel his Chi the entire time. That means he never suppressed it, nor did he have a reason to.

Krillen was gullible and placed more emphasis on what Goku told him the fusion would be capable of as opposed to what it could actually do. There is no reason to disregarded any character for any purpose.

The Super Saiyans on Kaioshins world got Kid Boo's attention. Goku in Dragonball Super was able to sense Kibitoshin from Earth. So really, Boo being sensed from the world of the kais doesn't necessarily mean much. His statement suggests that he was sensing him the entire time as well.

 

[Evil Vegeta]

You just said Krillin was gullible and placing emphasis on Goku's word than reality. Why would you not disregard what he's saying?

It means a lot in the Boo saga. Super Saiyan 3 Goku's power reaching their world is considered a big deal. Now Super Boo replicates the same feat and it isn't?

If he was sensing him the entire time, then Goku wouldn't have questioned if the Chi belonged to Majin Boo. It was a sudden change that surprised him.

Because he wasn't sensing Boo, that much is clear. He just went along with what Goku said. But that doesn't give us a reason to disregard him as a character.

Vegeta was considered to be more effective against Pure Boo then Kibitoshin was, yet Kibitoshin can be sensed from that far away. Pure Boo looks into the cosmos and presumably senses either Goku/Vegeta SSj together or Kibitoshin on his own. It isn't really a concrete fact that SSj3 power only is the only thing that can be sensed from that far away.

He wondered why Boo's Chi suddenly changed, implying he sensed something before-hand.

 

[Evil Vegeta]

That means he's not a reliable subject to base anything on. His opinion is disregarding the reality that Super Boo is too much for Gotenks.

Kid Boo was in space. Maybe that could change things. No way of telling. The Kibitoshin stuff can mean anything considering he thought he could help Goku and Gohan fight Gotenks Boo. I wouldn't automatically put Vegeta above him. The only thing made certain is he'd be fodder to Boo and would just get himself absorbed.

Kibito: “Ab-absolutely unbelievable…To think that his power would reach as far as this sacred region.”

Power reaching their world is an unusual thing. It isn't something that happens on the regular.

Goku already knew how Majin Boo's Chi felt considering he's actually seen him close up. If you feel a mysterious Chi that's different than anything you've ever felt before, you wouldn't feel compelled to comment on it?

Krillen knows Goten or Trunks would mop the floor with him at the tournament, that's why he was so relieved to know they weren't entering. He calls Gotenks haughty, meaning that Gotenks was arrogant and overly confident in his own abilities. He could only know these things if he could accurately sense them and determine how they compare to something else. There is no reason to disregard a character because it doesn't work for you.

Super Saiyan level of power was an unusual thing to the Kaioshins, they hadn't experienced anything like it beforehand and could barely comprehend it. So I really don't see why being sensed from that far away is considered a huge deal.

The current evidence suggests that it isn't. Pure Boo sensed Goku & Vegeta as Super Saiyans or Kibitoshin on his own -which is more likely with the new material, and Goku could sense Kibitoshin from that far away. Does it mean he's comparable to Goku SSj3? No.

Old Kaioshin also implied that Kibitoshin wasn't anything special because he said Kaioshin wasn't beforehand. To me this suggests that he considers Vegeta to be the more effective option against Pure Boo.

 

[Evil Vegeta]

I already showed that Krillin can be laughably wrong in the face of his fear. He outright said 3rd form Freeza barely changed and Vegeta called him an idiot for not sensing the difference. Krillin is not infallible. Never was. Never will be. You also don't realize how this doesn't help you, since you're often one to insist the fusion of Gotenks isn't quite up to Fat Boo yet. Krillin's just plain wrong and completely stopped sensing Chi there. Piccolo isn't even sure why he can't understand that Gotenks is nothing to Super Boo. Come on.

A power reaching their world is a big deal. There's no way around it. Kibito says it.

Yes, and in that same new material, Goku can't even lock onto Freeza's Chi, but he can lock onto Super Saiyan Gohan's. None of this stuff is clear-cut. The new material creates many contradictions on top of that.

Old Kaioshin only says he'd be useless against Gotenks Boo. His power was never factored into the battle with Kid Boo because the Saiyans were going to fight. Old Kaioshin also was surprised they weren't going to merge in some form to challenge him, so there's that.
