Did it REALLY SHIP? I DO NOT trust the tracker.
yours was really fast
Build time - 13 to 16 = 3 days
Build to ship - 13 to 19 = 6 days
Ship to 'butt in seat - 19 to TBD = TBD days
I have been in builds since 1/17, already 2x as many days as you. However, the tracker updates seem to lag 2-3 days. i.e. it updated to ship 1/17 on 1/19, 2 days later.
My dealer says ship schedule is 1/28 - if true, my build to ship would be 17 to 28 = 11 days, we shall see.
As chip design engineer, my habit is to try and measure everything, including variance - mine looks roughly 2x yours.
