reading is easier. In some works, such as Gibbon's The History of the Decline and Fall of the Roman Empire, the fog scores using the old and revised algorithms differ greatly. A sample test took a random footnote from the text: (#51: Dion, vol. I. lxxix. p. 1363. Herodian, l. v. p. 189.) and used an automated Gunning Fog calculator, first using the sentence count, and then the count of sentences plus clauses. The calculator gave an index of 19.2 using only sentences, and an index of 12.5 when including independent clauses. This brought down the fog index from post-graduate to high school level.
