So here's a way a number in that +5-7 range might have helped us figure Miss Kitty out, Denise. On 2/22 she had a 200 for the evening shot. She got 2 units, which could have been a little high. If it was, and she dropped low midcycle, then the next morning's 334 would have been a bounce up from the low the night before. (a bounce is when her body senses a lower number and releases extra sugar)
Once we know what she does on that 2 units, it might work better to give a little less for certain preshot numbers and a little more for others. But without the midcycle numbers, we're only guessing what is happening.
