Tips for an accurate result
Re-check readability after editing, not just before — edits meant to simplify text sometimes accidentally make it more complex.
Keep a style consistent across a document; wildly varying sentence complexity can hurt flow even if the average score looks fine.
Don't over-optimize for a score at the expense of accuracy or nuance — a technically simpler sentence that's less precise isn't actually an improvement.
Compare your result to similar published writing in your field as a benchmark, rather than an arbitrary universal target.
