They are fairly well approximated as ellipsoids of different sizes. Typically, I want pieces around half the volume of the smallest potatoes, but with the range of sizes, this means cutting the larger ones into at least 5 pieces. While it would be simple to make parallel slices giving equal volume, these would have very different shape to the halved smalls. Some can be quartered to give nice chunks, others into thirds with 2 perpendicular cuts...
Surely this second part is false? Most of us have got used to high levels of salt in modern diets, and prefer the taste of salty things even when we've had way more sodium than we need.
