Absolutely, break the arc into user stories, set up A/B tests for each twist, then track time on page, scroll depth, click‑through, and sentiment lift. For a single plot point, calculate an engagement score, funnel drop‑off rate, and net promoter score change—feed those into a weighted KPI dashboard so you see if the twist actually increased retention or just caused a brief spike in scroll fatigue.

Right, keep the narrative voice in front of the metrics, not the other way around—otherwise you’ll end up with a data‑only screenplay that feels sterile. Use the numbers as signals, not as the plot itself.
