Call it

Does it fly within 30 minutes of the current schedule? Judged against the schedule as it stands when you call — a slip proves the delayed-callers right. No calls on this one yet — be first.

Planned times, published by the launch provider and carried by Launch Library 2 — not measurements. No public feed streams a rocket’s altitude or velocity during ascent, so this site does not show any. Times can move, and a hold moves everything after it.
