When do Apple Stores in China mainland restock the iPhone Duo?

We’ve seen 16 iPhone Duo restocks in China mainland since November 2 at 7 Apple Stores. 25% came between 2 PM and 4 PM, store local time. Half of the restocks we saw sell out again were gone within 14 min, and 63% within 20 minutes.

From our own checks of Apple’s in-store pickup availability over the last 30 days: every store at least every 15 minutes, and stores people watch about every 10 seconds, so short restocks at unwatched stores can be missed or look longer. Free to quote with a link.
