Hi Kaori, Happy New Year.
You are doing a great job with the food.
Looking at the spreadsheet numbers, it seems that Utyun, when he drops fast he does so quite early, so by +2 he sometimes has dropped by a very large amount.
If we want to try and slow the drop, to try and control the bouncing, we need to get in there early with the food, before he drops so far.
With my Cat/ George, he would go fast but early, many times by +1 I would know if cycle was going to be a dropping one, so I would almost always get a +1, then if drop was very fast then I would try some MC(13%), or higher LC like 9%.
For George the +1 test was usually a much better indicator of how fast he might drop, so getting a +1 allowed me to make a decision about food and stay ahead of the insulin.
The bright green numbers are not 'real' Kaori is using a human meter, and hasn't dropped below 50, however, because she first started with an AT meter the SS is formatted as such, hence the confusion
I'll reply to this on your condo, with the language issues Kaori has I don't want to muddy the waters.
