That slight change of AoA at 05:41:22 - ish, is also troubling me. Why there? Why so consistent before and then after the change? i.e., if it can change at all, why would it remain steady either side of the change?
Given the oil damping system and inherent friction it would be reasonable to expect the weight to stay put and not respond to vibration or minor changes in g.
.
The forces on an operating AoA vane/system would be high compared to the weight which is just there to balance the vane.
It is not like the weight on a balance beam scale that is part of the measurement.

I think the change at 05:41:22 - ish and one slightly after that can be explained by 2 brief excursions to ~.5g (bit hard to tell exact from graph) at the same time.
Each of those might have 'bumped' the weight enough to shift it slightly.
