Extrapolating from the crunch week is just wrong. It featured: 1) A temporary production line 2) Reworked cars included in the total 3) 24x7 production, all hands on deck 4) No downtime for maintenance 5) Went on for 175 hours, not 168 6) Whatever else that went on that's not public (almost certainly some stockpiling of parts) Maybe you can draw some inferences from the outcome but N x 50 is not the way to do it. Output will certainly drop in the short term, it's just a question of how much. In the long term, maybe they'll do better than 5k a week, maybe they'll eventually reach there as a steady state, but even the latter isn't guaranteed.
