How to calculate the constellation? What is 100% accurate?

Constellations belong to western foreknowledge. Eight characters and six hexagrams belong to the intermediate prediction of Zhouyi in China! Even if Zhouyi predicts the highest, it is impossible to be 100% accurate!

Modern scientific prediction, such as weather forecast and DNA detection, can't be 100% correct!

So there is no 100% accuracy.
