May I ask from which information did you base your number count on? Yes, there are more than 30 A-Ranks, but excluding operators there are only 31. As for the B-Ranks, there could be many more unknown units that the manga nor anime has revealed thus far. The estimates are not random at all, nor are they completely off. They are sourced from page 9 of Chapter 7. Information directly sourced from the manga is counted as accurate, unless I am mistaken. I suggest you to consider all the facts in the future before you make incorrect assumptions.
