I agree with Bobbi -- Creamsickle likes to bounce. It may help to keep in mind that bounces are hugely annoying but they are a normal part of the process.
A couple of thoughts...
Stick with one meter. Most people here uses a human meter for a few reasons. The dosing methods -- both TR and SLGS -- are written based on values from a human meter. Strips for a human meter are widely available (including nights, weekends, and holidays) vs for an AT where you have to have them on hand. The human meter strips are also much less expensive. Going between meters will also make you cross-eyed.
If you get a pre-shot number that is lower than you're comfortable with, you have three options -- stall (without feeding), shoot a reduced dose, or skip the shot. Doing more than one of these options in one cycle (e.g., stalling and shooting a reduced dose has double the effect on the depot. Ultimately, you want to be able to work your way down to shooting low numbers. Start thinking about what approximate number you'd be comfortable shooting.
Keep notes in the comments section of your spreadsheet if you aren't sticking with a dosing method. For example, I haven't a clue why you shot 1.0u at PMPS on 5/17. There may have been a great reason but if you're wanting help with interpreting your kitty's SS, it helps to have all of the information easily accessible and in one place.
While your kitty is bouncy, he's clearing the bounces pretty quickly. This means more work for you since there's no way to reliably guess when the bounce may break and numbers may go from red to blue or green. So far, Creamsickle is in very safe numbers. However, given the size of the drop, there's a good chance you'll see some bouncing given a drop of over 200 points by +5.
The best way I know of to try to flatten out the numbers is to do everything you can to prevent your kitty from earning a reduction. You want to maximize the amount of insulin while using food to prevent a reduction. This allows Creamsickle's body to get more accustomed to lower numbers vs panicking when he's in blues.
