IFT12 acceleration off the pad was initially faster than IFT10/11, similar to IFT6, but started to outpace all after 30 s. They throttled the thrust way back, almost half, for max Q, but then found another gear, rapidly increasing to 2 g (could have been more if not for the loss of 1 engine) until hot staging. Unfortunately, with the new status bar layout, there's no booster speed display for about 80 s after hot staging, so can't see if there was a negative jolt that could have contributed to the boost back failure. The ship started fast, then dropped to around 0.5 g after losing one RVAC engine. Looks like maybe they monitored the situation for about a minute, then throttled up the remaining engines, eventually hitting a peak of about 4 g at the end of the burn. No evidence of limiting the thrust at 3 g, as appeared to be the case on some earlier flights. There are a couple of glitches in the data, due to unusual behaviour in the video telemetry, most noticeable at 68 and 437 s.…
