I don't know if there is truly any rhyme or reason to the timing and the tracker status. Mine sat in the "Production Begins" status from 5/23 until yesterday morning 6/6, when it then skipped three status marks and changed to "Entering Assembly Line". I wake up this morning, and it's already on "QC". My CA told me early on it depends on whether they have all the parts on hand for the build, for what that's worth.
