If I’m understanding the question, then I’d say probably so. But I wouldn’t have any tips for it beyond understand the theory really well, or plug that MC arc into the software and trust it to pull the IC signposts for you.
I haven’t looked much at PRCO, but my understanding is that it’s a spatial view of a quad analogous to an electric circuit. It’s not a view of how conflict increases from one signpost to another, but rather a view of how each corner of a quad...I don’t, affects, or interacts with conflict. The intensity of conflict in each signpost isn’t prescribed by the software. It is, as all things ultimately are, up to the author. Though it does seem like a dynamic that might have a place in a future, more dynamic model.
Things don’t have to get progressively worse. They just have to deal with conflict. Let’s say you have a story about treasure hunting. Sp1 is Obtaining. Obtaining the map to the treasure means stalling the lord of the manor while someone else sneaks in and grabs the map from the safe and the police are nearly called. But once the team is out of the house and has the map they can now move on to Doing. Obtaining the map created conflict, but it didn’t make things worse for the characters who can now start the actual treasure hunting. As far as they’re concerned, things are better. And the the conflict was intense. And then maybe hunting treasure leads to the loss of all their supplies, and now things are worse, and it was more intense. Then they learn that there’s another way to the island. Better! And the conflict was really very subtle. And then they understand that the treasure was just a metaphor for what they had all along. Much, much, worse! Though very mild intensity of conflict.
Though, to be fair, I think if you set the outcome to Success, then your characters should tend toward “successful” resolution of signposts to some degree and if you set Judgment to good, then the MC should tend toward seeing things as progressing in a “better” direction to some degree.
