Nobody here ever stated you could get 46MPG on a daily basis under normal driving circumstances. The data you reported from fuelly sounds about right for someone that is driving primarily in a suburban environment - and its what I'd expect to get if I was driving in such an environment.
The expanding hot diesel thing is certainly a real issue, however that is only an issue if your re-filling from a tank that is fairly full - if you're checking mileage after the reserve light has come on and you've got 1.5 gallons of 'hot' fuel in a 21.5 gallon tank I don't see it as a significant factor.

Yeah but who drives at a "constant 50MPH on a flat road with no headwinds on a nice day with the tires inflated to 40PSI and the A/C off. " .
Very few so that's almost never.
