See your logic ManaAdaSystem, but ADS-B was reporting "airborne" 1013 altitudes from much earlier in the take-off roll (first one at 93 kts GS with 80% of runway still ahead), and QNH was reportedly 1029. I'm not buying a sustained climb as early as deltafox44 either just yet. And claiming only 225ft achieved in 16 seconds from rotation - in a Cessna maybe? Doesn't ring true as any 737 number for me. I don't see anything close to continuous at that point other than the velocity. Everything else is just granular data and straight lines between points may not be helpful.

How did we get any intermediate 1013 baro report of 7075' anyway if runway elevation was 7625' and QNH 1029? Is there a big dip ?
