I made 2 orders. My second order is arriving today, I'm waiting for the device as we speak. My first order was a 16" MBP M1Max custom config. You can see more details about my two order's status and specs here on this
post thread. Updated status on this post
here. The thread is shorter, about 13 pages but keep in mind there are also international buyers on that thread.
You can search by this thread by user name. I bookmark a post that I'm interested in so I can jump back to the post at a later time and skim through to the most recent. I will also always try to post quote reply someone so readers/lurkers can click on the post quote and jump to the original post, skim down and through back to my post (with a post quote reply) incase there were multiple people referred who responded inbetween.
There's a group of us who had shipments with the same tracking data from Shanghai China all the way to Ankorage Alaska before the shipments split. My guess is due to customers selecting "expedited shipping" vs regular.

Edit: Also, quick note. I would not try to estimate international orders against U.S. orders. I think Apple has pre-determined stock ready for each country and so some international buyers are experiencing huge jumps ahead in estimated delivery vs actual delivery. There seems to be delays for U.S. custom configuration orders for 16" MBP.
