Storytelling Analytics Features

High-complexity features with the highest community engagement potential. These turn raw data into narratives.

11. Clutch Factor / Last Stand Classifier

• What: Auto-detect events where the outcome flipped in the final 20% of duration. Classify events as "Dominant", "Comeback", "Contested", or "Collapse" based on point progression curve shape.
• Fields: h1_event_snapshot (points over time), h1_event (outcome, duration)
• Viz: Event list filtered by type, with mini point-progression sparklines
• Wow factor: "Season 4's final defense was won with 3 minutes left — the biggest clutch in history"

12. Perfect Storm Detector

• What: Find the single 15-minute snapshot with the highest compound stress: peak players + lowest win rate + most simultaneous active events
• Fields: players, successful_missions/missions, active event count from h1_event
• Viz: Single highlighted card with timestamp, context, and severity score
• Wow factor: "The Worst Moment in Helldivers History" — instant water-cooler conversation

13. Coordination Paradox

• What: Does more players = better outcomes? Scatter plot of successful_missions/missions vs. players. Find the efficiency sweet spot and the chaos threshold.
• Fields: players, missions, successful_missions, per-faction
• Viz: Scatter plot with trend line and annotated sweet spot
• Wow factor: "15K players outperform 40K players at defense missions"

14. Planet Heartbeat Waveforms

• What: For every event, show its point progression as a heartbeat-style waveform. Contested events = jagged dramatic lines. Easy wins = smooth. Losses = flatlines.
• Fields: h1_event_snapshot (points over time per event)
• Viz: Mini waveform per event in the timeline, expandable to full chart
• Wow factor: Players who fought for a planet for 3 days will recognize the shape of that battle
