A Cheddite plastic case measures .025" of work hardened plastic.

It might hold 3 BAR. Let's say it will hold 10 BAR (145 PSI).

At a working pressure of 800 BAR, that is (at the very maximum) a percent and a half.

That's lost in the noise of shell to shell variation.

The Earth is an Oblate Spheroid.
