If he thought he was above Goku, like he usually does, then he seeing that Goku was above Gohan would be enough for him to believe that he was stronger than Gohan.
Wrong. Vegeta says he's stronger than Gohan after Goku fights Yakon, yet Goku's fight with Yakon is when Vegeta realized Goku was still stronger than him.
There is no reason for Goku not to think he doesn't need SSJ3 here considering the villains he's faced in the past episodes. General Rildo for instance. He would be able to save Vegeta easier by becoming transforming into a SSJ3, which he assumed would be more than enough to fight him. And then use the massive difference to his advantage. Kind of like how Majin Vegeta knocked out the kids with the massive difference in power between them.
Goku never assumed he would be more than enough to beat Vegeta, he said if he'll withstand Vegeta, he'd have to do it as a SS3.
It's pure speculation that when Bebi Vegeta says he has the greatest Saiyan power that, that would include a character that doesn't exist any more.
Except it's not. He was stronger than every other Saiyan at this point, Vegetto was the only one left to be surpassed.
Goku not going full force against Vegeta initially is based on nothing at all, and there's nothing supporting that.
That's pretty much what I said, he underestimated Vegeta then realised that Vegeta, the way he was then was enough to give him a good fight.
That makes no sense. If Goku's punch wasn't full force, how would be able to tell Vegeta was more than a match for him?
You're honestly reading too much into the wording of this sentence. I have seen this sentence used in numerous literature and for the most part it just means that the two people are a match for each other.
No I'm not. Goku says Vegeta is more that a match for him, simple as that.
Goku can't be stronger than someone that is more than a match for him, that makes no sense.
Yes, he pretty much is
Except he's not. You literally have nothing supporting Goku being stronger than Vegeta.
Goku's only punch to Vegeta does no damage, while Vegeta's punch to Goku does damage. Your only rebuttal to this making something up like Goku was holding back against Vegeta which is baseless.
Seriously, please explain how Vegeta doing more damage and avoiding more of Goku's hits makes him weaker than Goku.
I can't even continue this debate anymore, you twist simple things and grasp at straws.
Goku says Vegeta is more than a match for himself... because he is weaker than Goku...?
Freeza, who can't ki sense at all, was perfectly capable of measuring his own ki output in specific percentages, yet master ki sensors like Goku or Vegeta can't even gauge his own power in comparison to another?
Vegeta is able to tell he is stronger than Gohan, because Vegeta
doesn't have the ability to tell how strong he is?
Not a fact. An opinion. Which doesn't seem likely considering the other information seems to disagree with it. Especially the actual info coming straight from the people who made GT that says Super Vegetto rivals SSJ4 Goku.
Who said the info came straight from the people who made GT?
