Question Improve stability and accuracy of global coordinates

Hi, im in dev of an app that need good stability and accuracy with relatively a little scanning.
My use case only need vertical plane detection.
Now, my question is, enabling ARCloudPoint and adding an anchor to each detected point, can it make the stability of the global coordinates improve faster, or this is a waste of time?

I need the vertical plane the most stable as possible because then the 3D information go back to unity and do a "simulation" that provide info of shelve's products.

I attach an example that im doing when the plane is correctly placed and anchored to the shelve.

 

Thanks for reply, i will try that
