Which is more accurate, triple water method or auxiliary satellite water method?

Gui didn't turn ugly mountain to the right, but turned left, and the water came out from the first auspicious direction of the three-in-one water method. However, using auxiliary stars is a direct contradiction, isn't it?

My verification of the water law is more accurate than that of the Water Affairs Bureau in 312. The method of assisting the star is accurate, but it does not allow that conversion.

I just verify it myself, and I will do more comparisons in the future to accumulate the verification rate.
