It was very rough. ED selling price - credits - Residual / 24, and then add a few dollars (say $30 or so) for interest. Nothing on paper, all in the mind, and I probably didn't consider some incentives, or got them wrong.

But academic, since I don't think anyone will be able to get this deal on an ED car.
