Its incorrect to associate lower rpm's at speed with better mileage. Its just an assumption, completely unsubstantiated, and a reflection of the posters misunderstanding of how motors work. If this were true, every vehicle would be geared to idle for cruise... Motor efficiency is a function of several factors, rpm being only a small part, torque curve being the biggest.
Since you have your bike geared to where your riding right in the meat of the LC8's torque, your mpg is no worse.
I personally found that running 16/45 slightly boosted my typical range over what I got when I first got my bike. Now typically getting the light around 180-190 miles, and running big fat 175 main jets to boot.
