On vision pro, what is the max walkable distance in unbounded passthrough mode?

In passthrough mode on the Vision Pro, what is the maximum distance one can walk from the origin while keeping stable tracking?

Anyone? Is there a limit, or is it boundless? This is a pretty important thing to know.

Does it matter since an immersive space allows only 1.5 meter boundary? https://developer.apple.com/documentation/visionos/creating-fully-immersive-experiences

To rephrase, in AR mode, you can walk around, is that correct? In VR mode, you are limited to the 1.5 for now. So for AR mode with the passthrough video on, in which that limit is not imposed, how far from the origin are you allowed to walk around? Is there a limit, or is it essentially boundless and the tracking will hold for arbitrary spaces, or is it limited to some maximum boundary based on tracking limits?
