There
is doubt, though. Nothing outright states that he got stronger in that time, so you can't simply consider it absolute fact. Does the possiblity exist that he got stronger? Duh. Is it likely he got stronger? Probably. Do we
know he got stronger?
No. Why don't we know? Because it's not established.
So, how could you argue that he didn't get stronger? I already presented one line of thinking.
Every time we've ever seen Goku improve his power dramatically, he's done it in a very short time. Usually within the span of a year, sometimes even less.
Goku trained non-stop for seven years straight, and made it to where he was at in the Buu saga. How do we know he gradually improved that much throughout the entire seven-year span? We don't. Maybe he got that far in just a year or two, and spent the next 6 maintaining that power and gaining tiny boosts. No matter how far-fetched you find that, the fact is, when Goku was fighting Vegeta, he said "I thought I had reached the pinnacle of strength." Here is Goku telling us that he thought he had reached the highest point he could get to, within those seven years. Actually, saying he thought he had reached the highest strength
anyone ever could ("the pinnacle of strength")
So, what exactly even establishes that he
can keep getting stronger? And if Uub's potential is pure-buu levels, then Goku wouldn't be so excited about fighting him again if he had become a lot stronger, see?
