Question about the Destruction value for the human body

[MJF6219]

So in the "breaking all the bones in a humans body" calc in the Reference for Common Calcs page, it states "To get the fragmentation values, we need to use the compressive strength of bones. To quote Wikipedia, "bone has a high compressive strength of about 170 MPa (1800 kgf/cm┬▓), poor tensile strength of 104―121 MPa, and a very low shear stress strength (51.6 MPa)" (Mpa being equal to j/cc apparently) all of which are obviously much higher then the 4.4 j/cc fragmentation value of the human body on the Calculations blog. So my question is, the 4.4 j/cc fragmentation value of the human body doesn't include the bones of the human right? Like it's just the flesh, skin, etc? Or am I just not understanding something correctly?
