Analyze my retention graphs and show me the exact second people leave. Map the retention drop-offs: what happens at that timestamp every time? Show me the content surgery required: cut this part, expand this part, move this hook here. Calculate: if I surgically remove the retention killers, what's the reach impact? Give me the retention repair protocol: these patterns kill retention, these preserve it. Include: how to read retention graphs like x-rays, what common mistakes show up in retention data, and why your favorite parts might be where everyone leaves.
