Unfortunately, the real answer is that the exact same armor thickness has different protective value against cr and cut depending on the size of the wearer (and also the GURPS dr model is in general not very applicable to cr and cut, because unlike piercing an impaling, the protection from armor is not "stops everything until you get through it and then stops nothing", it continues to absorb a fraction of damage as the wound gets larger).

Also applicable to some impaling weapons - plenty of those have an ongoing taper along their length rather than being basically constant cross section.
