I can't remember how many it was, but they do seem to have been losing orders and gaining new customers almost constantly. IIRC someone recently calculated that, based on their position in the queue, they must have lost around a thousand customers/orders by a few months ago. I make no warranty on that calculation, but it should give some idea that the original date and time of order would not NECESSARILY be a very valid indicator of your place in the queue NOW. I mean - let's say you ordered after the 6 hours. You'd be in the second 2000 units for sure, possibly in the last 1000 units. But if everyone who either cancelled or failed to pay up was before you, you could be, potentially, as early as order number 1001!
Naturally, anyone who ordered within the first 6 hours will be even nearer the starting line
