The reason the bouncing is happening is that Miss Kitty isn't used to spending time in the normal BG range. The more time she spends in normal numbers, the less the bounces will occur.
I just want to offer a cautionary observation. You've seen some green numbers relatively early in the PM cycle lately. I want to encourage you to keep testing. It's possible that Miss Kitty may have dropped low enough for you to reduce her dose. It's been a while since you've done a curve or gotten multiple spot checks at night so there's no way to know where her nadir is. The nadir can change.
