What an editing pass is for
An editing pass is a decision that applies to every sentence, made once so it does not have to be remade each time. Facts first, then structure, then wording.
A generated draft has a predictable profile: fluent, evenly weighted, confident where it should hedge, unsourced where it should cite, and longer than the point requires. Each of those is a pass.
Editing in the wrong order is what makes the task feel endless. Rewriting a sentence that will be deleted two passes later is the most common way to spend an afternoon on a page that gets no better.
The six passes here take about an hour on a 1,500-word draft. The twenty-minute version is at the end for when that is not available.
