Working with a client right now going through Scene Construction with the PRCO, SRCA, TKAD, and PASS modalities - its going great and really helps to quickly point out any holes in the development of the scene. This client tends to blend Resistance and Current into the same beat (like blending IC and RS), so splitting it out like this really helps him understand what is missing from his story.
Compound that with TKAD and the writer can see that T, K, and D are already represented and then its simply a matter of figuring out what the A is for that missing beat.
In other words, he might have a scene with beats hitting Situation, Fixed Attitude and Manner of Thinking, but missing an Activity. He simply splits out the blended beats into different beats and finds an Activity that fits in there and then its off and onto the next scene.
I plan on writing it all up after I've gone through the whole thing. Learning tons.
