How often does DFW–SLP fly?

What does the route health score measure?
A blend of departure-side delay at DFW and arrival-side delay at SLP, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
