In general I think you will get a better response if you do a
better job of explaining why you are asking the question (referencing
sections of the specification and explaining why you think there is
confusion).
Without explaining why you think the specification is unclear it
is often hard to know how to respond.

Since currentTranslate/currentScale effect the mapping from any
element in the docuement to the user agent's notion of 'pixel', it
seems pretty clear from the definition of the method that they must be
accounted for in getScreenCTM.
SL> And also,

As to currentScale/currentTranslate - they are currently only
applicable to the outer SVG element and ignored on inner svg elements.
See Sections 5.17, 16.2 (SVGZoom event), and 16.7.
It is possible that currentScale/Translate will be expanded to all
SVG elements in the future, but currently the specification clearly
limits them to just the outermost SVG element.
