Firstly, with as little personal input as possible:

my notes:
. FR24 claim to use "FAA data", what it means I do not know, however the recorded altitude seems to be corrected for QNH (which is not the case with ADS-B raw values)
- For ADS-B raw data, speed = ground speed
- Typically for ADS-B raw data, altitude = 0 means "positive weight on wheels", not the actual value
- ALT = 0 at time 23:40:34 should be interpreted with extreme caution as the speed for that frame is invalid.
Based on the above, the time lapse to slow down on ground from 135 >> 132 kt is 18 seconds, which translates to 1200 meters of distance covered. This is ignoring the suspicious reading at 23:40:34.
Fact: LDA = 2100 m
Observation: B2N2's quoted figure of 4600 ft = 1400 m.
