It's probably worth mentioning (this argument might come up) that the critical exception is Ultra-SS, but this is notable because it was such an exception, and in that case getting too bulky made you slower. If there's a disparity based off the manga, then it should make Kibito slower than someone smaller with the same ki, not faster (so he could compensate).xmysticgohanx wrote: But power level increases every stat.

If ki increases every stat roughly evenly, then Kibito being physically weaker than Base Gohan means it should be lesser in all physical ways (do we really want to say he could out-skill Gohan?). If ki can increase stats unevenly because of body conditions - and the manga shows it can - then the evidence of how this works means that due to his bulk Kibito would be even slower than you'd expect, not faster (which has been suggested to get around the implications of that scene).
So yeah, Kibito should be lesser even if you include evidence that contradicts your first sentence. Doesn't say anything about Kai, since Kibito may share a similar role and power relationship with him as Popo does to Kami.
Incidentally, this wouldn't be the first time I think the manga contradicts the Daizenshuu on an issue concerning Gohan (I won't say what it is, to avoid an off-topic [censored word]storm).
