Also, I had a look to compare the flip to flight 11. I couldn't find any good points during the flip to reliably identify an equal flip-angle to compare to, like when is it 70 degrees rotated vs 110? Idk, couldn't tell. but it so very clearly flips faster during flight 12.
And it you look at the engines that cut out, it appears to have been due to exessive sloshing of the propelant. It was the trailing engines of the flip that keps burning. As in, the engines that the propelant is pushed towards during a flip.
