Calculating and visualizing Gimbal angles.

Thank you!
I would expect the initial motion to be more consistently in the same direction opposite the flight path of the object (rather than the very inconsistent evidence I showed above) if the bumps were caused by sudden decelerations the object made before starting to rotate
• sudden deceleration should be visible against the cloud background, but it's not
• sudden deceleration should at first be compensated by the fine tracking and not cause a bump
