How accurate is Zhuge's divination?

I'm telling you, "Su 'an, the God of Zhuge" should be exactly the sixty-four hexagrams obtained by the superposition of gossip, thus giving birth to 384 hexagrams, because there are six hexagrams for each hexagram. Future generations will explain what happened in the last life. Because of the huge fans of folk Zhuge Liang, the Ming Dynasty even praised the embodiment of wisdom. Named "Zhuge Shensuan". It comes from the unconscious mind of fortune teller, the perfect combination of strokes of Chinese characters, gossip and sages. Measure the future development trend of things. The inventor's wisdom should surpass Zhuge Liang, a famous minister, politician and strategist at the end of Han Dynasty.
