Profiles are matched by their physical conditions, including flow state, reference dimensions, boundary inputs and transition assumptions—not rounded Reynolds or Mach labels. Each line uses that profile’s available cached curve. Samples are curve values, not additional solver runs.
Some displayed estimates have uncalibrated prediction error; no validated accuracy guarantee is claimed for them.
The summaries use each displayed curve’s angle range; a maximum at the edge of that range is not a certified stall point.
