That will work, if I compare mine on week 32 and @5pot on week 33, theres approx 2.5K difference when we omit the last 3 digits to give a fair bit of accuracy. Let me update the spreadsheet as is without the ordering on the order number as only other 2 members (@5pot and @Rhurs) have posted their order number.
Here it is now with the 1st 5digits of your order. Which makes the week signed the order form a pointless reference as the order number is the accurate reference.
Would be useful to update me with the order numbers of the members who have picked up their cars or advised as being built or In Transit.
My Order Number 31444***.
Ordered by me 25/8/21, but the "Detailed Order Information" screenshot shows Order Date 27/8/21, Acceptance Date 1/9/21.
This screenshot also shows Original Date 10/11/21 (which was week 45) and Forecast Date 13/12/21 (which was week 50).
My Original Build Week was 202143, which became Confirmed Week 202146, from the "Vehicle Detailed Information" screen.
I suspect that these week numbers may relate to the start of build, whereas the dates above may relate to completion of build.
