I guess realistic is a subjective term then in the Poser Community, it seems to mean what is generally accepted as realism rather than what is actually realistic purely because of the content available to the average user.However that still doesn't answer the OP's original question it just gives two sets of answers from two opposing camps. I think I had better stop now, I've even started to confuse myself and I'm not sure what is real or not anymore.
