# What are the specific formulas for measuring 'flywheel velocity'?

**Open question.** For [[concept-data-flywheels|Type 4]] investments, the financial logic depends on measuring *flywheel velocity* — how fast the AI improves per cycle of operational data. The article gives the conceptual definition but leaves open the **mathematical or operational formulas** needed to track this velocity across different industries (e.g., agriculture vs. software).

**Resolution path.** Publishing industry-specific case studies detailing the exact mathematical KPIs that data-science teams use to track model improvement per data-ingestion cycle. This gap makes it hard to compare flywheel strength across a portfolio and is the practical bottleneck for acting on [[action-invest-closed-loop-systems]].
