Apart from the announcement that the center core failed to return correctly, it appeared from media coverage that the flight went exactly according to plan, but there is always the potential for glitches that can affect the flight even if not obvious to a "bystander".
Did anything else about the Falcon Heavy test flight not perform as planned besides the center core restart/re-entry/recovery? As I understand it, the launch could proceed successfully with less than all engines running. Did all 27 engines of the 3 cores start and run nominally for the full duration of their planned ascent burns?
As I understand it, not everything went as hoped for all of the "recoverables", and there was some variance in Starman's final trajectory (a bit farther out than expected), but I'm wondering if anything went off-nominal for anything related to the payload ascent that would affect confidence in future payload delivery.
