There aren't enough entries in that fuel log to make any sort of statement, beyond, "hey, I'm doing pretty well". Seriously. One needs at least one year of entries before being able to say much one way or another.
The hottest part of the year and the coldest part of the year aren't going to give the best numbers, and "why" is central to the "problem": None of us feel as well as we do at these calendar points as when the temps are moderate. Doesn't matter what theory may predict. No good thing comes overnight (which is a few months) and immoderate temps only make it more difficult.
Some of us have been driving a decade or more before you were born, I'd guess, and driving for best return on money spent . . this means we've all had to change habits as we've gone along. And it's not as easy to do the laser beam concentration as when we were 26.
Look to some other aspect of ownership: Do you have a garage? (why not?) Have you some other project (stereo, other upgrade) that will take some of this energy? Etc. Let the miles accumulate by taking a step back for awhile.
Reality check: What's the annual average $ difference between 31 and 27 mpg? How much?
Never let feelings box you in that you cannot find another outlet for them. Every aspect of ownership/operation deserves your attention, not just mpg.
