What is the actual tier for crushing HEADs

[Bonnie09]

I've been Wondering this for a long time

My way to do this is this one

Skull volume: 1400 cc
Brain volume: 1260 cc

Fragmentation volume for Bones: 4.4 j/cc
Fragmentation volume for human flesh: 0.4 j/cc

1400 * 4.4 = 6,160
1260 * 0.4 = 504
6,160 + 504 = 6,664 Joules or Street level

For violent fragmentation
Violent fragmentation volume for Bones: 7.533 j/cc
1400 * 7.533 = 10,546.2
10,546.2 + 504 = 11,050.2 or Street level+

But i want to know if this previous calculation is wrong, i'd like to know the ACTUAL Tier for Skull Crushing

Idk if there's a violent fragmentation volume for the human flesh

I read in another thread it was wall level.

I read in another thread it was wall level.

It isn't, wall level is too high

9-C. 3000-3800 J. It was concluded in this thread.

The volume x destruction methodology was proven to be inaccurate for skull busting given that battle rifle calibers and above have no issues smashing the skull to bits.
