Basically, it is possible to multiply power from low 2-C to 2-C and divide from 2-C to low 2-C, we just don’t know how much is necessary to close the gap. Because of this, we never assume a multiplier or chain from baseline low 2-C is enough to reach 2-C without concrete proof within the series, because it could just as easily be a 16x gap as a googolplexian times gap. Looking at it from the other end though, since we don’t know if the gap is finite or infinite, we take the assumption that results in the lower rating, which is that it’s finite, and therefore dividing by a finite amount places them in the high end of low 2-C rather than lower in 2-C.
