12-B:  -2 dimensional

To be infinitely weaker than someone who's infinitely weaker than someone who's 0 dimensional. Low 12-B is when you're -3 dimensional, -4 dimensional, etc.

12-A:  -1 dimensional

To be infinitely weaker than someone who's tier zero. High 12-A is when you're -0.9 dimensional, =0.8 dimensional, etc.
