B787E
I'm not going to explain every step, but you need to think of this from a commercial, not technical, point of view.
Your suggestion would show a structurally very heavy aircraft (high OWE) as being efficient, even if it carried a small payload.
As we said, you need to know the payload. You need to junk the irrelevant info (the times..) and request what you really want. If they won't give you the payload then ask for the OWE and deduce it.
It looks like an A310 size plane, so guessing the data should not be so difficult. Happy hunting!
P.S. be careful not to confuse litres and kg.
