I've never understood the fascination with week of manufacture. Just sayin'.

I think the reason some compare weeks, is if defects start occurring with certain iPhone models, they compare the weeks to see which was manufactured if their iPhone may or may not experience that specific defect during that manufacturing week.

Have manufacture weeks ever shown to correlate with a particular defect? I'm really asking.

There is no real definitive answer to that. What happens is, is certain defects are discussed upon other iPhone owners of what they are experiencing with their new iPhones. For example, A yellow display. So naturally, other iPhone owners start asking which week was other iPhones manufactured during which week that others are experiencing with yellow displays. Then those iPhone owners speculate that "Week 33" might be a bad week for the iPhones that were experiencing yellow displays. Again, there is no way proving this. But they use it as a reference to determine where their device falls in line when it was manufactured on what week.
 
So iPhone 8/8+ entered manufacturing in August, makes sense. I guess iPhone X too went into manufacturing in August, or maybe September.

I know how it works. I was just asking if there had ever been any proven correlation.
