Start hereOpen ¶1 on the left. Ask two questions of it: what does this paragraph do for the reader, and does it deserve to stay as it is? Rereading lets you follow the argument you meant; this table shows the argument you actually built.
Two rules make the whole diagnostic work. If you cannot summarise a paragraph in one sentence, it is doing more than one job and needs splitting. If two paragraphs get summaries that sound the same, one of them goes.
