Why this curve

This curve combines the stored NeuralFoil prediction with 1 contributing CFD observations. History windows remain observations, not separate solver runs or automatically converged points.

Model uncertainty is conditional on the stated assumptions and has not been calibrated for this condition. It is not a validated accuracy guarantee.

Geometry fit: RMS error 0.05202% of chord; maximum error 0.2448%.
