Good morning, Summer.

The phrase refers to Lantus's ability to keep lower numbers flatter rather than pulling numbers down from higher ones. Look at Ruby's SS from this year. There have been a few precipitous drops from preshots into lime numbers, but that is few and far between. What you mostly see are preshot numbers, both blue and green, dropping 20-40 points at onset, rather than 100-150 which you often see with Susie going from pinks or yellows. You also don't see many bounces. Once you're in those lower numbers and the cat's become accustomed to them, no more bouncing.
See PM cycle, 3/29: shooting a number like 68 is encouraged because a) it's
not going to zero, b) it might drop to 50, but that's not a
huge drop because it's being helped by the preshot meal, and c) it will stay steady and allow the kitty to stay in those numbers it needs to heal the pancreas.
I won't lie: I still got nervous shooting numbers below 69. It didn't happen often with Ruby, but when she did I monitored. And look, we all survived to tell the tale.
I encourage you to really study Ruby's SS and at the spreadsheets of Butters and Lyla and of Jax and Susanne. They are veterans of Shoot Low to Stay Low and the examples I always looked to for encouragement when I got scared and eventually learned that everything would be all right. Just like you will be.
