→ Vertical Stability: Stop wild swings in revisions (e.g., Dec forecast changing drastically each week)
→ Horizontal Stability: Eliminate erratic zig-zags across your horizon
2️⃣ Quantify the Chaos: Measure instability with MAC (Mean Absolute Change) & sMAPC (symmetric Mean Abs % Change)

In real-world settings (retail, energy, finance), planners care about stability just as much as accuracy.
Volatile forecasts disrupt operations, break trust, and increase costs.
SMAPC is designed for rolling-origin and live evaluation—perfect for high-stakes environments.

📊 Symmetric Mean Absolute Percentage Change (SMAPC) is a powerful, underused metric that quantifies forecast revision—how much your forecasts change between runs.
How much does your model "change its mind" when new data arrives?

🚨 Forecast Accuracy ≠ Forecast Stability
We often obsess over accuracy metrics like RMSE or sMAPE to judge our forecasting models. But there's a hidden trap: a model can be accurate yet unstable—constantly changing its mind with each new update.
That’s where SMAPC comes in.
