Marko - there's a difference between a softar and a naturally smooth negative. Doing stand/semi-stand development creates micro-contrast which can over-emphasize details where you don't want them. As I said in my original post, portraits are a subject that you don't want semi-stand for, which if I recall correctly was the original question you asked. When I'm shooting subjects with lots of fine detail where I want to bring out that detail, and where I've got a naturally low contrast subject, I do semi-stand to bring out that detail and boost the contrast into a useful range.
