Is “Scale of the uprising” true?

In the novel, Fang La and Song Jiang are both listed among the Four Great Bandits; according to the "History of Song", Fang La's uprising affected six prefectures and fifty-two counties, shaking the southeast, and its actual momentum and scale far exceeded that of Song Jiang's band of dozens. The original text states: "宣和二年，方腊反，江、浙震动，调兵四方" (History of Song, Biography of Han Shizhong)
