I don't have the issue, but 1 square foot with a thickness of 1" has a weight of roughly 5 lb * Density (so 40 lb for 1" steel). Max DR is probably empirical, realistically the reason you don't use Kevlar against rifle-class threats is because it has poor scaling (realistically, given how GURPS DR works, the DR of fiber-type armors should vary with the square root of weight) and generally performs poorly against high velocity attacks, not because it has a true maximum.
