Good summary. I was pleasantly surprised that they nailed the re-entry target even after the ascent engine problems.
The re-entry itself looks amazingly smooth compared to V2. TBD whether it's good enough for re-usability (much less rapid re-usability).
But Flight 12 was definitely forward progress.
It looks like the ships software did a phenomenal job compensating by adding that much longer Second stage burn time. It was also very cool to see the sea levels vector to compensate for the thrust asymmetry. All and all that ship is look really realllllly good. Seems like they just need to add some mass to Raptor to reduce the tendency to tear itself apart..
1 out of 33 failing hardly seems like a tendency - probably some minor issue. Relight was likely an issue with new downcomer that was supposed to improve boost back engine feeds for its flip maneuver - that seems to need work.
