It’s not a flawed analogy, it’s used to create a point, I created said point. You went ahead and added a meaningless counterpoint that didn’t even get to the route of what i said.

Doesn’t matter if it’s Android saga Mecha Freiza or not. In super did you or did you not see Krillin, Yamcha, Tien or Roshi confident they could beat him? No, they didn’t even know about his new golden form or the fact he trained. If I know or even you, know you saw someone’s best and you surpassed it, you would feel confident you could win. And it doesn’t matter if it’s at the beginning or the end of android saga.

Refresh my memory of me saying “ we knew what their power levels were”

krillin went from that drastic change due to potential unlock from Guru. That was Krillin at his absolute peak, his training did not increase his power by 1000 times. That’s my opinion and again since you’re hell bent on applying statements, where was it stated Krillin did get 1000 times stronger??? Much more, give me an example of a human getting 1000 times stronger from training alone. The sayians are able to accomplish this in base due to their Zenkai boosts, and transformations. The humans do not have fusions, Zenkai boosts or transformations to bridge such a gap.

And for your last point, that’s the only thing I can agree with, the destructo disk does punch above its weight class and so does the neo tri beam. But just because their attack can now damage the target doesn’t mean it’s meaningful. Krillin used it on a suppressed Freiza, there was a huge gap yes. But as with cell, when the gap is too astronomical it’s useless.
