Oh, it's really nothing to be impressed about. It's a simple mathematical equation, really. You first have to figure your total rise and total run. Then decide the rise of your first and third steps, and here's some trivia: Since my total number of stairs is odd, you have to use the measurement on an odd step, not an even one. More on that later. Now, when divided by the hypotenuse triangulated by the seventh's step's width, that gives you the total run you need between stringers minus the ledger's thickness offset by the footer's length. Adding into that, make sure to recess the top landing to make up for the thickness of the planking of the decking material to be used. See? Pretty elementary, really.
As evidence of the handiwork, pencil lines (and two black marker lines located on the 4th and 9th steps, added together, makes 13... an odd number to match my odd number of steps
) are clearly visible on the outer edge of the stringers closest to the camera. The extra 2x4 bracing adds more mounting surface for supports I still need to add later on. Under the stairs will be a feed storage room with shelving, a chandelier, and possibly a wine chiller.
Cheers
