Dude that armour is like T7-8 (maybe earlier was a bit of an exaggeration, but not by much) at least. Look at the advancement humanity has made in armour construction, we've gone from a plate of mail to a Kevlar vest, which is more than five times as effective.[b] That took like 1000 fucking years, imagine how far ahead technology is that's 50x Kevlar[/b].

:lol

Also problem with the multipliers is that they are only really relevant in reality for specific situations.
The only universal protection is density (at least when it comes to impacts, particle radiation is a whole different issue).
