I would guess all the parts are pre made and in stock for boxing and shipping. I think the electronics with the software and hardware components have to be assembled and tested for each detector. A wild guess would be 500 per day or 2500 per week and every time they have a to fill a Sea cargo van they ship somewhere. Remember this is a world wide release. They keep telling us they will be caught up with pre orders by the end of March. No one knows how many pre orders there are. My really wild guess is they had close to 100,000 pre orders..
Remember packing the boxes for shipping is manual labor
