Very interesting that livestream count-up stopped at T+18s right as the PAO calling pitch-over maneuver, well before it started overcorrecting and had gone sideways(figuratively and literally) on camera, and then resumed erratically from T+41s. Aren't T+ times tracked externally for trajectory calculation purposes, in parallel to being timed onboard for control purposes - like, guys at the pad clicks his stopwatch as he sees a green light and yells the reading into the phone ASAP so that guys in places like Hawaii or Africa knows when to start waving their dishes in a sweeping arc, while the vehicle itself operate valves and fire mechanisms as it sees fit? I'm just a space fan, but if they were taking T-time on stream from vehicle telemetry rather than just one-shot syncing at launch, I feel that's rather original, and, absolutely no offense, but find it very German.
