As with all data the devil is in the details and getting more of it means we have a better sample size.Be careful with the data for us that ordered in May and June (even July). There is time in there that is essentially a pre-order. That is, days passing before Jeep was even able to make the 2023’s. So the order to production time is artificially high due to that.
Also since you are collecting data, they never told me when mine shipped but it was delivered September 2nd.
ordered-to-scheduled and scheduled-to-production are probably highly correlated to what you ordered (availability) and the dealer (backlog). That means both of these entries are likely not a great predictor.
production to built and built to shipped is probably going to be fairly uninform with some variance depending on what day of the week and if any holidays are between start/finish.
shipped to delivered is going to likely be location dependent but I wouldn't expect it to be very long in general.
Here is the current data. It would be awesome to get about 20 more samples though.
