Well, yes...and no. You see, Dr. Saxton's calculations are correct, but incomplete. He grouped the Emperor, Grand Vizier, Darth Vader, etc in a group he dubbed: "Emperor of other nominated proxy or executor". Okay, emperor being Palpatine and leader of the Empire. Nominated proxy being someone like Vader or another such person with such power, though no real political or military leadership/command. Executor, lastly, being someone who is not emperor, but has de facto powers or powers close to that of the emperor.When Elvis suggested his insignia to be the seven red over seven blue insignia without the code cylinders, it made me realize that an emperor does not share his insignia for that person is the highest ranking person throughout that empire. Thus, an insignia for that emperor should/must exist that is above all others (history has proven such with kings, queens, emperors, dictators, etc since humans are naturally egotisitical and what I explained), that, in this case is the insignia Elvis chose for himself. So that got me thinking, the seven red over seven blue without cylinders insignia is that of emperor, therefore the seven red over seven blue with cylinder must be that of a nominated proxy (i.e. Vader) or executor (i.e. grand vizier). So, that is why I presented this insignia again. I told you patterns get monotonous and, ultimately, boring. Sigh. Now, of course, politicians, proxies, and exectuors such as Palpatine, Pestage, and Vader did not wear military uniforms, so these insignia would never have been seen (unless they ever truly decided to wear one or a coup occured where the military took over...I suppose). Well...there you have it: another strike of the grand imperator of BEAK. Sigh.
