One other thing that fascinates me is that, while drafting Act 1 I was still trying very hard to use the PSR, and I made a mistake. I knew a few important interrogation scenes were coming up, and I saw that PSR #1 of OS SP2 was Investigation. So I assumed that an earlier event was the act turn, and that the interrogations took place at the beginning of Act 2 (because of how well they seemed to fit Investigation).
But it turned out I was wrong, the Act Turn hadn’t happened yet – the interrogations were squarely in PSR item #4 (Worth) of OS Act 1. And reading the draft now, I can totally see where some of that Investigation-focused stuff falls completely flat, like it’s missing the point. Meanwhile, there is a bunch of Worth stuff in there that’s pure gold (thank you muse).
My lesson learned from this is that, it’s cool to outline your story using PSR if you’re consistent with it. But if you’re going through it more loosely (like I was, and like I think I always will – I can’t write from a detailed outline), you may be better off using the PSR as a vague guide, being careful not to force anything.
