and I picked 80,000Lbs as it's broadly the mid-spec for the Trent 900

I think you need to read that example more carefully.

It calculates, based on NASA data, that a 747-200 in the cruise generates around 16 MW per engine.

The Trent 900 develops roughly one-and-a-half times as much thrust as the JT9D, so around 24 MW per engine.
