If the M1 iPad Pro launch was any indication, it was about three weeks from preorder to first delivery. It could have been scheduled that way to allow some flex time, it could have been a result of supply chain constraints. Either way, that's about a one week addition to the typical pattern. That said, that's not a rigorous way to look at their supply chain situation. I'd guess Apple is pretty solid on their iPad and iPhone lineups. Mac is probably a mixed bag and M1X chips in the fall refresh may lead to longer delays in getting product than folks are used to.
