GIMBAL looks just like a jet aircraft on thermal camera.

GOFAST has been conclusively shown to be a slow-moving object at about 13,000 feet. It's simple geometry. We don't know what it is, exactly, but it's probably a balloon.

So GOFAST is probably a 3 or 4, while GIMBAL probably is a 6 or 7 but even more pedestrian.

That's a fair assessment.

However, I'd add that the two figter pilots who testified in front of Congress would NOT agree with the balloon assessment. So, if you accept their opninions as SME and thus leaning towards legitimate then that leaves "a slow-moving object" before you add in the details about the acceleration patterns that also occurred.
