On second thought, why can't Krillin have used his weighted power in the image training? He was wearing his weighted shirt if I recall correctly. And if weights suppress the usage of ki, I don't see how he could unleash his unweighted power in the image training.
24k?
I don't see why Non-Enraged Gohan has to be stronger than Weightless Krillin. Also, I think Krillin must get a bigger boost from removing his weights. How about giving him 1.125x (half the 1.25x boost Goku and Piccolo got by removing their weights)? My numbers are:
Krillin (weighted) - 1,480...
That statement had a different purpose, since we already knew the power levels. The purpose was to show how weak Vegeta treated that range of power.
But on Namek, the purpose was to inform us about Gohan and Krillin's powers.
Should we infer from Jeice being helpful in Ginyu vs Goku that 50% is the minumum percentage? On the other hand, Jeice's interference turned the tables immediately, so maybe one can be useful with even less power. On the other hand, maybe Jeice wouldn't have been helpful if Goku had known from...
I think the symbolism of the oozaru image when Goku's potential was unlocked was that Goku's full potential = Oozaru power, so FP Goku post water = Hypothetical Oozaru Goku.
Why not? It would've killed Fat Buu, who's not much weaker than SSJ3 Goku, had it not been for regeneration. That being said, I've started feeling maybe we shouldn't give PLs to suicide explosions, since maybe their mechanics are not exactly the same as those of blasts.
