Those "calories burned" calculators are also not very good, so you may just be in the margin of error.
It's easy to calculate how much energy it takes to propel a given weight 5 miles. It's hard to tell how many calories a person burns to produce that energy. Your ratios of aerobic to anaerobic respiration are going to impact that wildly, which will depend on how much oxygen your body can absorb and how quickly you're burning through oxygen. There's a huge gap in the amount of energy cells get from each. Aerobic respiration produces up to 38 ATP per glucose, while anaerobic produces only 2 ATP per glucose.
Running form probably plays into that as well, if you've got some kind of suboptimal gait or you're swinging your arms a lot or something like that.

Yep, my form is atrocious and inefficient due to bunions and Morton's toe which has evolved into hammer toe.
I'd argue that I burn calories more efficiently, however :)
