According to my records, that puts you in
week 13 of the preorder stats. I wasn't writing them up in so much detail back then, and the records I used to use have since disappeared, so I can't tell you what the numbers were on that specific day, but you're somewhere between 840 and 852, and if I assume the orders were made roughly linearly (even though they weren't even nearly that) that's put you on about 846, although there tended by the time I was actually writing them up for there to be something of a weekend effect, so you might be slightly lower than that.
