Is the six-year prediction really accurate?

I have been a diviner for a while and have helped some people solve problems. Objectively speaking, I think:

First of all, the six hexagrams are practical and accurate, otherwise they would not have been circulated for so long.

Secondly, the accuracy of six hexagrams is not 100%, and 100% is a god. From two aspects, the accuracy is relatively high when we look at the divination level and the mind of the fortune teller (that is, honesty and dishonesty). Generally speaking, the divination of pure mind is relatively clear, and the divination of emergencies is relatively clear.

Furthermore, I personally think that Yi Xue has always affirmed the development of things, and Liu Yi can see things and avoid them.
