  **p_ratio1** is an upper estimate of the prosperity ratio computed by `(1 -  Nsph*4/3*pi*r^3 / vol_geom)` where `vol_geom` is comptued by the `grep xyz` with zlen = (zmax-zmin-8) for 8=extruded length. The more pebbles, the more accurate this estimation is.
  **p_ratio2** (WIP) is computed directly inside user file.

  see the `peb_cal.ods` for the explicit computations
