This sort of catastrophic failure only really happens with Kevlar and cloth style armor. Basically if the bullet hits with enough energy to exceed the strength of the fibers then they can't "catch" the bullet. In that case the only energy lost by the bullet is the energy needed to break the fibers in which case a DR of 1 or 2 per 10 points of DR the armor has seems about reasonable though keep in mind I'm not an expert here on this subject heh.

IIRC, DouglasCole used to work with Kevlar before and has done experiments on the failure models for it so hopefully he'll be able to chime in on the matter.
