I think that the book will help you immensely. When you are using injected insulin you have to be aware (as you seem to be) that the insulin action is prolonged. It will still be working for a couple more hours so you have to take that into account.
A rise from 7-13mmol/l though is too high.(unless you are a toddler) Have a look at this article by Scheiner, the author of Think LIke a Pancreas , it may help you think about the various issues.

I would also record menus and look for patterns. Personally, I need to take into account eggs when I bolus. There are many threads on here about insulin and protein. Anecdotally there are some people that find eggs need a little insulin (and some that don't ; we all have our own idiosyncrasies.
It will certainly help to have some input from a CGM ( I think that's the monitor you mention) .
One thing that struck me:
Nothing works well if you haven't got your basal and ratios correct. I would look at basal testing. Your pre meal reading was at the top of the range, but your bolus ratio is high.
According to a website Vogel bread has 16.7 carb per slice ie 33.4 carbs for the two. At 1unit to 2g carb (is that really what you mean?) then you will have taken as much insulin for one meal as your total basal. That seems lopsided . I take about 45% basal ,55% bolus and I don't particularly restrict carbs; a low carber might have a higher percentage of basal and a lower percentage bolus

I can't accept that all diabetics need to cut their carbs to achieve a good HbA1c. Whether anyone ' needs' to reduce them, or change their type will depend on what they ate before[type] and what their activity levels are at the moment[amount] ) .
It's 10 years this month since diagnosis My endo congratulated me today on my consistent results over that time. My carb and calorie intake have varied considerably depending on what I've been doing. Training for a marathon or backpacking then carb and calories go up . When backpacking I end up eating large amounts of carbs. Sitting on my backside at the computer, I need less fuel and have to take that into account.
The purpose of injected insulin is to replace non existent endogenous insulin and allow the body to function .(insulin has many roles) One could say it's most crucial purpose in type one is to prevent DKA and death (reducing carbs won't prevent this,it might delay it. There are malnourished people in developing countries diagnosed with low/normal blood glucose and DKA)
What we need to learn to do is to adapt the use of insulin to a healthy lifestyle
