What is the justification (numerically) for 4-B ACTUALLY?

[Chritin]

So I was looking at the attack potency page as of recently and noticed/recalled something about the 4-B rating. In terms of its justification, it's simply stated to be the energy needed to destroy a Solar System equivalent our own. This is all well and good on paper, but then you consider the actual quantity of stuff there is in the solar system. Technically, around 99.86% of the solar system is JUST the sun, which we already use as the basis for 4-C. Thus, if 4-B is just the energy needed to destroy the mass of the solar system, it would be insignificantly larger than 4-C, and even smaller than High 4-C. I feel like I remember this being brought up before, but I can't seem to find what was said about this topic and where 4-B actually comes from.

Notably, 4-A has an explanation that 4-B doesn't.

• Multi-Solar System level:Instead of doubling the value of Solar System level, the distance between two such systems needs to be accounted for as well. The calculation for energy required to destroy two solar systems was done, with the following assumptions:
  • Distance between them as the minimum distance between Sun and the next closest star, the Alpha Centauri.
  • A spherical blast, strong enough to obliterate the contents of both solar systems at the same time.
  • Hence, the value obtained is the energy required to destroy two solar systems at a realistic distance.

This leads me to believe that 4-B was calculated in a similar vein (maybe being the energy of a spherical blast covering the range of the solar system), but I can't find any math on this number.

Your initial point is correct; if 4-B was just the combined GBE of everything in the solar system, it wouldn't even be High 4-C.

The justification for 4-B is the same as for 4-A, just applied to a single system. It assumes an omnidirectional, spherical blast that covers the entire volume of the solar system, not just the destruction of the matter within it.

We just apply that same logic to the radius of one solar system for the 4-B rating. That's why there's a huge jump in energy from High 4-C (ending at 2.923x10^45 J) to the high end of 4-B (2.008x10^57 J). It's accounting for the vast distances and volume, not just the mass

Do you know the exact numbers/calculations for that number?

EDIT: Nvm I found it. Kinda odd that the explosion is based on the explosion of neptune at a range, but considering the GBE of the sun is so much lower than the energy needed to destroy neptune at that range, I guess it makes sense.
