<p>Zaphod: As you are our voice of experience, perhaps you can enlighten; had dinner with some retired officers and wasn’t paying total attention. They said that of their “class” of 1000, there was a very specific numerical correlation, something like (and here I need help) that one became Admiral at the top of the pyramid, and then the decending numbers were in a specific proportion, i.e. the leap to above Captain was a huge one. Can you illuminate?</p>
