How come a uniform can't be made of 40% to 90% life fibers?


I've noticed that on Kill la Kill that Goku Uniforms can only be made from
10%, 20%, and 30% life fibers. But later on, it is revealed that a Kamui is
made of 100% life fibers. That seems like a major gap to me. How come a
uniform can't be made of 40%-90% life fibers?




No characters we see can wear 40%-90% life fiber uniforms who cannot also wear
100% life fiber uniforms.

The only people who can wear 100% life fibers are not 100% humans (they have
life fibers experimentally infused into their bodies). No pure humans have
been shown to be able to wear more than a 3 star uniform.
