The user manual put "*initially* scaled to Unit Centroid Size". I am not sure if there is some untold meaning in using "initially", which seems to suggest CSinit controls whether to initially scale to unict CS while finally, objects will anyhow scaled to unit centroid size.
I am not trying to explain anything. Just got the same question and would like to invite more expert opinions.
