As with all data the devil is in the details and getting more of it means we have a better sample size.
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.
