Bounces can take six cycles to clear. That's likely the length of time she's taking now as she's not used to lower numbers. There may be a bit of New Dose Wonkiness in there too.
I read back to yesterday, and glad you increased. The goal is greens - increase every six cycles if you aren't seeing anything under 200. Regardless of whether or not she's bouncing, a dose with yellow nadirs is too low a dose. At one point, someone told me the saying that one of the earlier members, a vet tech, said about where you are now. "Be the tank, a tank always gets where it's going". Be aggressive as TR lets you me, it's still safe. You want to get to that zone where she's seeing some greens.
