Don't be discouraged. There are many many factors, including temperatures, time of day, crosswinds, minor changes in driving style that none of us would detect but that instrumentation could show were deleterious.

And don't forget the possibility of pump error. It can swing your calculations significantly. Always do your fills with the tank closer to empty, always fill at the same pump, always choose the slowest automatic fill speed, always stop filling at the first click.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
