Yeah kind of. Think of a typical unnamed ki blast. It's not a sustained blast with a large diameter like a KHH has. Look at the difference of the Raditz KHH and the one against Freeza though. Against Raditz we see Goku charging his energy into a specific point. Against Freeza he's still continuing to fight as if he's not even charging up his ki. Really have to wonder if it's even possible to amplify when you're already amplified by 20x.
But we are still talking power level, are we not? A small little nothing ki blast with a power level of 1,000 is still 1,000. And a suped-up maxed out Kamehameha that has the power level of 1,000 is still 1,000.
Now, if those two powers clash, the Kamehameha will win out due to duration and size. Not necessarily more special destructive abilities. I think the extra abilities are already accounted for in the size and duration.
That's where I'm extracting the variable here. I think Raditz vs KHH is the same as Freeza vs KHH, the only variables being that the KHH Freeza tackles is way bigger and the duration is way longer. That's what I'm reading here.
In regards to if 20x can amp... I have to look at it again, there's gotta be at least some amp to justify it being a Kamehameha don't you think? Do you think Goku can use a regular ki blast to the same effect?
Also, doesn't it suggest there is amp?
KKx20 Goku lands a shot on Freeza, but then is easily dodged, surely he knows 50% Freeza > Kamehameha?
Well, this is where I like Hector's numbers here, small, but noticeable differences.
KKx20 Goku 45
50% Freeza 50
KKx 20 KHH 55
Freeza 60
Hmm, I don't like the spacing there with KHH so close to Freeza. Let me try....
Powered Up Freeza 80
KKx20 KHH 60
50% Freeza 50
KKx20 Goku 45
I think something more like that might work. In terms of what we are actually seeing. Which is this power chain...
Powered Up Freeza >> KKx20 KHH >> 50% Freeza > KKx20 Goku
Don't you think that's the proper chain?
