I think a human meter will really help you feel better about your numbers. It makes such a huge psychological difference!
Shoot through the bounce. There are a few ways it works, and if you read around over in Lantus you can see the variations, but basically it means that after the low number, you don't reduce the dose because you know that the next few cycles will be high anyway. The trick is that you are trying to time the reduction for the cycle when the bounce will break and the lower numbers will re-appear - so you don't end up overdosing. you have to really really learn your cats patterns. Usually there is a "tell" during the cycle before the bounce breaks. Often the flat yellow cycle. Some cats you can count the cycles and they will consistently break on the fourth cycle after the low (or the 3rd cycle....or the 5th cycle....ECID). Other cats you just have to learn to read their patterns, use mama-sense, and sometimes a little magic.
Of course if you get it wrong, you are steering and testing like a mad woman for a few hours.
It's not a game you want to play if you aren't home and able to test a lot, or if a cat is really unpredictable. I think Little is predictable enough that you could try it if you want to commit that much time, and if she's okay with that much testing.
