High tech armor vs Ultra-tech armor

It's a fair bit of work, but you could use the articles "Cutting Edge Armor Design" in Pyramid #3/85, and "Ultra-Tech Armor Design" from Pyramid #3/96. Together, they provide rules that should allow you to rebuild various ultra-tech armors in a way that makes them better than equivalent high-tech ones.

As I'm reverse-engineering the DR of the armor from the thickness of the armors, using the DR/inch rather than assigning DR and working from that as the articles call for, do we have decent approximations for how thick fabric (particularly concealed and tactical vests), scale, mail, and plate armors should be?
