I think Armando uses Signposts as sequences (four per structural act) and PSR variations as scenes -- either 4 per sequence (64 scenes), or 2-3 per sequence if you're using the Z-pattern (somewhere around 48 scenes). He describes how to encode static plot points into these scenes in the vampire story chapter. He also has the "Instant Dramatica" approach which comes up with 40 paragraph outline combining the static points with the signposts.
@jhull has a modified approach which uses 5 story drivers (1 initial, 1 final, and 3 for the act turns) + 7 scenes per act from the signposts (4 OS scenes using each PSR variation + 3 scenes from the other throughlines).
This all sounds confusing but if you map it out it makes sense.
It seems like all of these approaches can work, depending on how your mind works and how much detail and how many scenes you need. Or to put it another way, there's a lot of ways to skin the Dramatica cat. (Note to self: write a story structure book called "Skin the Cat!")
I have been beating my head against the wall on this for a while an have come to the conclusion that I'm way too much in weeds on this and that the most important thing is to just learn enough about my story to write the draft and try not to overthink it (easier said than done).
