Morph data maxima (in Pd object, maybe other too)

Trying out the morph object in Pd. What are the ranges for x, y and pressure? I measured the maxima and get this:

x: float 0...231.973
y: float 0...129.734
pressure: float 0...6009.38

I found the API values, but they don’t seem to correspond with what I can get from the Pd object:

I find these numbers a bit… odd? What’s the rationale for those? Also I believe they should be part of the documentation a.k.a the help-patch.
