Your first chart is quite interesting.
Here is what I see:
1. You are eating ALL the freaking time!
Take Day 1 for example.
Your fasting was 9.7
You inject your background and your quick acting (assuming you are on a 1:1 ratio) and you have your breakfast.
Your background insulin needs some 2-3 hours to kick in.
Your quick acting peaks at 1 and a half to 3 hours after injection and subsides at the 4th hour.
And even before your morning quick acting starts to work, you stack more food at 12:30 (and you stack more quick acting insulin too)
By 14:30 (that is just 2 hours later) you stack even more food…
You morning quick acting has just started to finish… your 12:20 quick acting has just started to kick in, you have barely digested your breakfast, and you are eating and injecting again…
How can you expect to figure out your carbs to quick acting insulin ratios in this way?
Indeed, during DAFNE course they tell us that we have the freedom to eat anytime we want and inject and control our blood glucose fluctuations but, this happens AFTER we figure out our basal rate and our carbs to quick acting ratios.
2. So, you almost eat every two hours, you keep stacking food and quick acting insulin and then, by around 17:00 ish, you decide to have supper. And then, you don’t eat anything else until next day 10:00 am which is 17 hours later…
In this case 2 things will happen: Either you will go low (because, even if you background insulin is set correctly, 17 hours on an empty stomach are too many for any basal insulin to keep your levels steady) or, you will sky high because your liver will produce sugar as your body is starving for 17 hours and needs energy to make it all the way to 10:00am.
Here are my suggestions:
1. Give, at least 4 hours in between meals so that you can check what your quick acting is doing.
For example 07:00-08:00 am / 13:00 pm / 19:00 pm.
2. Either transfer your dinner time later or/and add a small snack around midnight (not necessarily a carb one. It can be just a small 30 grams piece of cheddar cheese or 30 grams of nuts).
3. Start with the exact same amount of carbs per meal. For example, 30 grams of carbs for breakfast, lunch and dinner. Forget snacks in between unless you need to treat a hypoglycemia. In this way it will be easier to figure out your ratios for each meal.
4. A no carbs meal (to help you figure out your basal rate) doesnt work unless you are "in the zone" meaning that your bg is under 13 mmols. If you are above 13 mmols, even if you have a no carbs meal, chances are you will go higher because if you have high blood sugar, even the slightest activity like having a shower, will elevate your levels.
Once your figure out your basal needs and your carbs to insulin ratios, you can eat anytime you want.
I hope this helps.

P.S. At your second chart, the good reading that you had at 15:00 is not because you figured out your lunchtime ratio at 13:00. Actually, you havent. The good reading is because you stacked quick acting insulin at 10:00 and at 13:00 and the two injections overlapped (This is the reason why your dinnertime ratio 9+2 - which was the same as your lunchtime ratio,- didnt work)
