@9876: Other World most certainly does not have increased gravity. When Goku died, he didn't experience any increased gravity at the check-in, on Snake Way or in HFIL. He felt it as soon as he landed on King Kai's planet though. Additionally, his weight training in question happened on Grand Kai's planet, which could or could not have increased gravity. It was never mentioned once that anywhere other than the Capsule Corp training capsules, King Kai's Planet, Planet Vegeta and Voon (the home planet of Pui Pui) had increased gravity. I don't know where you are getting that the planets of the Kais are stars. Besides, even if King Kai's planet is a star, which it isn't, it was still stated to only have 10x Earth's gravity.
Again, I did not say stats didn't increase when power levels went up. I'm saying they don't multiply by the factor of the power level.
@9876: @flashback0180: I'm not saying a higher battle power means you aren't stronger or faster, etc. I'm saying the multipliers don't work. Having ten times the power level does not mean ten times the strength, or ten times the speed.
I will also mention that I love Dragonball. Seen it all, own it all. But multipliers simply don't add up to what is actually done in the manga or anime. I could point you at a million threads using multipliers where Goku can lift billions of tons and go millions of times faster than light, but based on actual feats and events, that is not the truth.
Great advice: especially follow above rule when calling out a mod.
Anyway, when they say stronger, they are referring to battle power. It doesn't mean he is 10x lifting strength, or faster, or any other individual stat. That's the problem with power scaling in the first place.
When we look at what actually was shown in the manga, that is the actual feat. Not a statement or a guess.
