Jeff, I know it is wondering off topic, but are you saying the cars were completely assembled in 1 day (give or take)?
If the start time was early enough in the day, an easy build (so that it moved out of the holding area quickly and back into the stream of things) documents suggest yes
Would love for you to elaborate as I have absolutely no knowledge of the time-frames (dates) and what they actually mean (you can tell I thought the buck tag was the completion date). To pose specific questions (please tell if I need another thread), What do the dates actually represent for example on my car: Build sheet date of K25, buck tag date of K28
Buildsheet shows an expected or projected date that someone guessed at when the car order was entered at the plant into the computer. Often off by a few days but have been examples (when there were production and release issues) of up to eight months that I've seen examples of. Very rare.
Buck tag date appears to be the day when there were enough panels put together to place the buck tag on the body - in most cases I currently believe were the same day as the car was started but sure there had to be a number of bodies that were started maybe an hour prior to that point that, at the end of the day, were not assigned a buck tag yet.
When we look at a collection of data from one car (example for NJ would be 68) we can see by comparing the Marti report finish date, the buck tag, the buildsheet and the door tag date we can see the similarities, close dates and the differences
and what all processes had to be accomplished from the buck tag date to completion?
Don't think we have enough space and that would surely take this thread way off thread. Basically 1,000 steps or more.
