I haven’t seen the movie or the analysis for Spotlight. I’ll put both on my list. Sounds like exactly what I’m asking about. Thanks for the suggestion.
So an example closer to the one i’m working on right now (i’m not going to give the actual story i’m working on right now as example, although i’ve given it in other threads. I personally love the story i’m currently working on, but think it sounds stupid when i say it out loud, haha. and yes, this example is probably going to sound a bit stupid out loud, too. oh well) would be of someone with a Fixed Attitude who is trying to show others through Activity that their Fixed Attitude is best. So think of someone like a personal trainer who thinks they know the best way to train even though others think their exercises are useless. So that attitude would be the IC story. Then the MC comes along and needs some personal training. So the encoding for the IC story is something about “the best way to train” and the encoding for the M/I is something about “training together”. There’s a slight difference, I suppose, but it feels almost like they are the same thing. Like two different stories in one encoding.
I’ve been going through the Sign Posts and Journeys and turning them into story points with the end goal of having a list of about 150 to 200 bullet points of everything that will need to happen in the story. Between the OS acts 1 and 2, I have about 100 points. Between the M/I acts 1 and 2 I have about 10, and that’s stretching it.
What I feel like I’ve done is encode the IC and M/I together into one throughline so that all the right issues and concerns and elements are covered. But I’ve left out anything personal to the IC, which doesn’t bother me because I don’t feel like that’s necessary to the story. I just don’t want this idea to turn into a book, and then the book turn into a movie, and then the Dramatica Users Group analyze it and decide it’s not a GAS because it’s missing a throughline. If they do, I’m blaming you, @MWollaeger. 
But seriously, considering what you’ve said, I feel like I’m probably still on the right track. Thanks again for your time.
