My experience has been exactly the same (I have not picked up yet - will pick up on Saturday). Had to go back and forth a couple times with Chapman but final OTD price was within a few cents of what I calculated it should be.I had the same experience as Earlybroncoboy, mine was a Jan 2021 reservation.
I calculated the price based on the 2023 DORA I signed last fall, including Ford's private offer certificate and the % under invoice Chapman promised way back when. Steve worked with me to reach an OTD price that matched what expected within a few cents. There was a little back and forth to get to that point.
Good luck, I hope your experience with Chapman is as positive as mine was.
