So, if you've been driving three different GM 4x4s with the 5.3L since 2006, you should just ignore your own experiences with fuel mileage and go with what is posted on a web site then? Okay, got it.
Uh, no. Your experience is just that. It's yours. You can use that information for "you", but that in no way means that it applies to everyone else. Your driving behavior, load, altitude, fuel quality, tires, etc. etc. etc. can and will affect your results.
Instead, the rest of us should look at the results of many people, which should include a wide variety conditions and usage. The data should, and does, show a normal distribution. This isn't the place to teach this concept. But, if you are interested in learning, then I encourage you to educate yourself rather than get offended by the use of data to make objective decisions.
