>>13429544>>13430553That calculation is fundamentally wrong though. The episode shows that, inside the defined blast area, some buildings only had broken windows. So, the 3000 radius wasn't for the fire blast itself, but for the entire destruction caused by it, which would make the blast significantly smaller.
Then, they do a self contradictory calculation - using the official stat numbers to calculate the power of the Rising -> Ultimate progression, while disregarding the actual official numbers for the Rising Mighty Kick.
This is also ignoring how it had been shown that the explosion is at least partially caused by the reaction of Kuuga's kick with the Grongi's belts, not just Kuuga's kick by itself - remember, there was no explosion at all when Kuuga killed a clone grongi that didn't have a belt.
