Spacecraft sep complete. C25 burn to completion, over-performance for precise GTO injection, to save orbiter fuel.

Orbit is 6,000 km higher than what was intended. This was done to save orbiter fuel.

Massive overperformance, which is interesting. Seems happy about it, as it will provide more life, but how can it be so far off is wild.

They burned the stage to depletion rather than the usual launch sequence, where the closed loop guidance system shuts the engine off when the intended orbital parameters have been achieved.
