Hello Kaori
Sorry I wasn't able to get back to you yesterday, we have guests staying. I have limited time today also, guests are still here, but wanted to write to you about managing the curve with food and give you some links to discussions about this subject. I can imagine that the language issue makes it difficult, you are doing very well with Google translate.
I just took a look at Utyun's glucose numbers on his spreadsheet.
Lots of nice blue numbers on this cycle.

Today is cycle 6 on this dose and with the depot filling, we are starting to see what this dose can do for Utyun's. On TR you would hold the dose for at least 10cycles at this point, and on SLGS you would also continue to hold. Unless he earns reduction which on SLGS would be a drop to 90, and on TR it would be a drop to 50 (on a human meter)
(your signature says SLGS, but your dosing hasn't been strictly SLGS, if you are feeding only wet food and it's under 10% then you are OK to do TR if you would rather do this, it allows you to hold on to the dose for longer, hopefully this gets Utyun into good numbers for longer periods of time and that, in turn, can help with the bouncing.
I think that the way you are generally feeding is good (remember only LC snacks late in the cycle/boiled chicken breast) It's similar to how I routinely fed George, but one thing that I did was to actively change that if he was dropping.
eg if I saw a big drop at +2 instead of waiting to feed till +3 I would give him a snack at +2
eg if
Utyun started at amps 200 +1 190, the fact that number was about the same as amps, and I was not seeing a food spike would alert me that a drop might be coming, I would then give snack as usual, but instead of maybe waiting till +3 for next test I would check again at +2, if that +2 was 140, I would give his snack early. Checking again in an hour. The idea is to try to slow down the speed at which they drop, this might ultimately mean that you see them have higher nadirs, but it can help to flatten the curve.
Utyun seems to bounce up to black/reds after he drops to green, when he has just dropped to blue and stayed flat, he seems not to bounce as high and he appears to clear his bounce in about 6 cycles.
He is bouncing, but in the scheme of things he is not too bouncy.
Here's a link to a couple of great thread that discuss bouncing and feeding the curve. These were ones that I kept refering back to and they helped me figure things out for George.
Jetta/bouncing
Feeding the Curve/Tashie
On another note, if Utyun is still blue (or his number is dropping) at preshot, I would post a new thread, link this one and ask for help, with his bounce clearing it can turn into an 'exciting' cycle, and you might want to have some company for moral support just in case he does get into reduction earning numbers. I would look out for you if I could but will be entertaining our guests so I won't be about.
Use the ? from the drop down list and try a catchy phrase like, Utyun pmps 123 shooting low/bounce clearing please help.
Talking about shooting when a bounce is clearing take a loo at this next thread/ post #6
Shooting a dropping number
The link above covers a lot of other areas too, and is one I found very useful.
If for some reason his number was dropping at PMPS and shot without posting I would be very watchful in the early part of the cycle, definitely grab a +1 and +2 BG test. Then take if from there depending on the numbers, monitoring until you see him flat or rising. Remember that on SLGS your no shoot number is 90.
Please ask if you have any questions, I'll try and look in, but can't guarantee it will be today.
