For me, the set points are usually mental. I hovered at 203 for three weeks and as much as I want to say it was a plateau, I think it was me freaking out over onderland and then doing a little self-sabotage. The same thing happened right before my BMI went from obese to overweight. It's annoying that I tend to pause right before major milestones, but I am recognizing the problem so hopefully I won't have as many in the future.
Also, in terms of hovering, when I lose weight I tend to woosh & hover. I might lose 5 lbs in one week then nothing the next two, I think that's just my body adjusting. So for you with your set points it might be similar, your body is adjusting to its new smaller size.
