You're changing the goal posts now, since when was this conversation about gimbals 10 degrees off or more off? It never was.
If a gimbal is way off, do the level calibration and compass calibration to make sure the gimbal IMU and Solo's IMUs are in sync then retry. Then contract support. 10 degrees is a significant amount and doesn't tie in with typical examples. Unless of course you're plucking figures like 10 degrees out of thin air just to continue an argument.
I measured mine at 13 degrees, so nothing is being plucked out of thin air. Calibration does nothing with regard to the issue. Mine may indeed be an extreme example, but the issues remain - it may be less noticeable on less extreme examples, but they ARE there. No goal posts are being changed, Solo is simply not functioning as you suggest it is or should.
My screen-record example and Joe's video disproves several contentions:
-His balloon IS at the center of the orbit point because it remains stationary throughout the video. You've simply picked camera frame center, NOT orbit center. The ground continually moves beneath your suggested orbit point, proving it's not the actual orbit point.
-Solo is NOT compensating for an offset camera rotation.
-You can NOT set an orbit point offset from a subject and keep the subject stationary throughout an orbit.
3DR may indeed intentionally rotate the camera to keep the left leg out of the camera's view, but they have NOT compensated for this in the flight controller and/or during smart shots.
