Now this may have been posted in one of the earlier 371 pages of this thread, but I came across this description of the various stages of the build process.
I'm guessing this is what Blood sees when he looks stuff up.
Receipt Date: The date that MS&S recorded the order.
When the order is received from the dealers
Serialize Date: The date that MS&S transfers the order to MP&L and the VIN is created.
When the order is received by Material Planning and parts are ordered
Segment Date: The date that MP&L determines which week the order will be built.
When they figure what week that parts will be able to be delivered to the plant to build the vehicle
Sequence Date: The date that MP&L determines which day the order will be built.
When they figure what day that parts can be at the plant to build the vehicle
Blend Date: The date that MP&L determines when the order will be built within the assigned day.
When they figure the specific order that vehicles will be built. This depends on options and line constraints.
Produced Date: The date that VO finished assembling the vehicle
Your unit has been built!
Gate Release Date: The date that VO transfers the vehicle to Transportation Carriers for shipping
Your unit has left the building, and is in the hands of the shipper (rail or truck)
Ship Date: The date the vehicle left the Assembly Plant
Your unit has left the load site, and is on it's way to the dealer
Arrival Date: The date the Dealership received the vehicle
Your dealer has the unit in hand, doing the dealer prep thingy
Sold Date: The date the Customer picked up the vehicle
You came in, looked it over, said, "I'll take it!" and signed the papers
