After considering the Doppler effect of universal gravitation, each cycle in the x direction will move 21 kilometers downwards and it changes very slowly in the y direction, thus providing a deviation of Mercury precession
> 14.76 " per Centuries.

Here are some cumulative data of the x, y coordinate offsets for each circle, they are obtained by the program simulation.
The unit is meter.
up= 3380, left= -10601, down= 3380, right= -21273
up= 3381, left= -31811, down= 3382, right= -42560
up= 3382, left= -53033, down= 3383, right= -63857
up= 3384, left= -74266, down= 3385, right= -85167
up= 3386, left= -95513, down= 3386, right= -106489
up= 3387, left= -116770, down= 3389, right= -127823
up= 3389, left= -138041, down= 3389, right= -149169
...
These data are approximate estimates based on program simulation data. But the final result
>14.76 " is close to
43.11".
