I'm wondering if there is a good way to tell which archive page a post came from. I essentially just need the post's position in the total order, then divide it by the 'posts_per_page' option. The hangup I'm having is getting that position or offset of where the post sits.
EDIT: All while being on the SINGLE POST template.
There, no matter what, the usual $wp_query global and 'page'/'paged' query vars are always 0 - so those won't get me anywhere.
