No, not at all, because as the guy below you in your link said, the guidance was 50,000-55,000 and "we expect an average of 5000 Model 3s per week" was a random offhand comment by Musk. He's probably thinking of the operating rate (ie average cars per day) and not the overall rate, since the operating rate is the statistic that he'd actually be capturing. There were 63 work days in Q3, and IIRC there were about 8 days of planned shutdowns, which would put the rate right at 5000.
Countering your nitpick with another nitpick seems inadvisable, but like... you're blatantly ignoring the actual company guidance to focus on a single random remark that was still essentially right. That's just goofy.
