My guess - it's a long a slow process of new data integration in the the rankings.
Interesting. By new data do you mean something along the lines of other signals and the bouncing is actually "different scoring" rather than intentional?
So, basically more factors = overall score changes?
And what could those factors be that cause a "bounce" after we make changes when pages were stable before? Something "user behavior" related or "time to 'trust' the change" like a 301 not always being trusted immediately, maybe?
