So, IMO, there's no way to get a particle's wf from a double slit experiment, even a rough approximation. Consequently, ME's are not enough to get a particle's wf by observing distribution patterns on the screen. And to correct my previous statement, if we don't know which-way in double slit experiment, we get two overlapping peaks, centered on the screen, opposite the space between the slits.
