I find this subject interesting because I used to do alterations of people's clothing as a part-time job (and still do for my children) and always had to estimate sizes of arms, legs, waists, chests, necks, etc. However, after looking at a variety of photos of various LSPGers, in the buff, I have to say I'm really not sure if I'm either over or underestimating their length or dimensions in general. Of course, it doesn't help that I don't have the type of LPSG account where I can increase the size of photographs. Nonetheless, your findings do seem to correlate with Madame Zora's observations, and whenever Ms. Zora speaks, I listen.
