I would put the AdjBBox before the Expression nodes. That way the values won't just be repeated outside of the format but they will continue growing/shrinki ng and will be usefull for images with overscan.
Also while your STMap is correct, there is a simpler Expression:
(x+0.5)/width, (y+0.5)/height
This way you only need one Expression node. The reason for the 0.5 is that the Expression node defines the bottom left corner of a pixel as its origin, while the STMap node uses the center of the pixel.
