You only burn 500 lbs an hour total at cruise? I don't think that is anywhere near correct.

Our avg taxi time in DFW is around 12 minutes.

With the APU running (400 lbs/hr) and one engine running (800 lbs/hr) you're at 1200 lbs/hr. Not accounting for increased fuel flow to SE taxi on the operating engine.

In most scenarios it's a wash or close to it.
