To be fair, the depreciation for production tooling is on a per unit built basis, but there are other items like buildings, etc., that are on a time based amortization schedule. So, the overhead should also scale linearly, with a small slope. I do think at ~6K per week, the margin will be in the high teens this year, but will improve to low to mid 20s by next year.Here is a simplistic model on margin. Some numbers such as overhead and material cost are WAG based on Tesla's projection. The main point is how quickly margin can improve when you start mass producing. But Q1 will look bad for sure.
