Is there any number that can define the Accuracy of the viewshed (and visibility) gp tools?

Giving the pixel size and the Accuracy of the height value can we get any formula that say that the real value (where an area is visible or not) really can be up to half a pixel times the max different from the real height of the pixel (just an example).

Somebody asked me and I do not have an answer.

Thanks

There is some discussion in Viewshed2

How Viewshed 2 works—ArcGIS Pro | Documentation

which also considers earths curvature amongst other parameters
