Hi @acivit, welcome to the forum
The precision of the Body Tracking does depend on the distance, the farther the subject is, the bigger the area the pixels represent, and the lower the accuracy.
We do not have an article about the detectors’ precision, but we plan to release something of this kind once the 4.0 is not in the “Early Access” state. For now, a lot of our resources are dedicated to improving the body tracking accuracy and performance, it changes every week really.
Best,
Jean-Loup
