When you say the feeds have been "picked over", are you referring to people searching for the "hot packs" like the one seller on eBay has been listing? I still don't get how that guy is doing that. I was at a Target yesterday and I tried to see if I could "see" the chase card through the back of the pack and I just couldn't do it. I guess if you had a lot of practice you could do it but I can't imagine standing there in the store and searching through 48 packs. It seems like that would take forever.
It seems more than likely that he/she figured out the pattern, colliation, knights move kinda mathmatical equation where as they have somehow concluded for example, that there would be a special insert card in pack say #23 to 26 of the pile into the gravity feed. But wouldn't the packs get mixed up during transportation and handling of that gravity feed. I suppose you could tell once the box is opened if the packs have been disrupted.
Also, someone else here has stated if the person figured out this, then why dozn't he/she just open up the pack and sell the special card themselves?
Also, they would of have spent quite a few ducketts to find out this pattern within the boxes.
