I agree, and I'll again stress the significance in case I failed to do so adequately before: you've misapplied your own method obtaining answers that are off by a factor of 10.

I agree, but I'm not sure what you mean by this. By definition, lateral stress cannot be less than hydrostatic (or "geostatic") pressure.
Hydrostatic pressure means that pressure is equal on all sides. If you accept that earth's pressure is static (or "hydrostatic") then one wonders why you've decomposed lateral and vertical stresses in the first place. They must always be (more or less) equal.
Your assumptions, method, conclusions, and execution have thus far all appeared flawed. You might do well to revisit each.
