What changed: slow share 46% at worst → 0% now

Of 27 aircraft that landed at National (DCA) between 7:59 PM and 8:59 PM EST and have reached the ramp, 0 took 13 minutes or more from touchdown, at least 10 minutes over the airport’s typical 3.4 minutes; the median was 3.8 minutes. Usually 4% take that long (this airport, the last 7 days). Measured by Tailodds from FAA surface surveillance; it does not show why. The slow share has stayed at or below 12% for 31 minutes across 16 checks, each with at least 10 landings and current data.
