Again, Freeza can sense ki, so he would know where Gohan compared to Piccolo and Ginyu was able to gauge where Goku's true power was on Namek, he thought Goku was at 80,000, so he was only 10,000 off the mark. Also, if it was only skill, Piccolo would be the most dangerous since he isn't rusty like Gohan.
Talk about a sudden "u-turn". If you agree that Ginyu can gauge Goku's "true" power without grasping it fully, that's all the more reason to believe others may have done the same with Gohan. Besides, what does skill have to do with anything? It was just a statement that Gohan held inside of him power superior to that of Piccolo. We know that Gohan, at bare minimum, can't output as much as he wants to, so even in that case the statement would not be nearly as contradictory as implied.
The fact remains, Piccolo did get around one-hundred times stronger off scene since even if you say Piccolo was equal or stronger to base form Gohan in Resurrection 'F'.
He still did overall better than Piccolo. So even if the margin is small, base form Gohan was above or equal to Piccolo. Also, Freeza, Tagamo, and Ginyu all acknowledge Gohan as being the strongest despite seeing Piccolo fight. While you can guess if Tagamo knows what he's talking about, Ginyu is very good at guessing someone's power even without sensing ki. He got closed to guess Goku's true power on Namek, outside of the Kaioken. Freeza outright can sense ki, so he should know if Piccolo was above Gohan, especially when he didn't know Gohan could become a Super Saiyan. Also, the fight with Freeza's soldiers is nowhere near as taxing to the Z-Fighters as the movie since they haven't been fighting that long.
That's still a tired and weighted Piccolo who gets owned vs. a Gohan who still literally can't even
scratch Tagoma, as seen in the video in case it was needed, so this type of reasoning is again
entirely up to debate; same goes for what you think of how physically taxing the Freeza fight was. I also don't see how that's supposed to disprove anything I've said. There's no statement having Piccolo making that kind of gap, and it's not exactly intuitive either.
Using Hit is an error since Hit was purposely holding back so he wouldn't kill Goku and he didn't take Goku seriously. This is in contrast to Tagamo, Ginyu, and Freeza who did take Gohan serious, Tagamo to the point that he killed his own comrade to wipe Gohan out.
... That's the point, actually. What makes you think we should all conclude Tagoma
absolutely cannot be, since he immediately says Gohan is a weakling and is barely fighting back?
