Any practical reason for the constant denominator in Halstead's Difficulty measurement?

Joaquim V. C. Assunção @Joaquim-Assuncao

12 December 2017 1 9K Report

Difficulty = (n1/2) * (N1/n2).

Is there any reason (other than have a smaller number) for dividing n1 by 2?

Adicionaly, what are the main metrics based on Halstead's?
