I don't know, but the reason I made a visual representation of my EDDs was to make it easier to spot a trend. After a dozen and a half updates, a hint of a pattern is beginning to emerge. The original Jan-Mar EDD on order day was, of course, just a general range. The first update to Mar 3-31 was probably a more accurate best guess with each subsequent update getting closer to reality. I think had I not edited my order on Mar 2, I may have had the vehicle around Mar 7-16, but my edit recalculated the EDD to the end of March. When it became apparent to the algorithm that the vehicle couldn't be pushed out by the end of the quarter, it recalculated a wider and later range from Apr 2-16 before narrowing. I suspect that my turn may be coming up soon, but because of the effects of other orders and transportation logistics on my order, the range keeps sliding a day into the future until all the planets align just right then I'll get a VIN and the process will wrap up relatively quickly. Or, the EDD could widen and slide far into the future as has happened for some others.
