Is this what typical post-honeymoon BG curves look like?

I am slowly getting better after being very down lately. But one thing keeps nagging me.

I keep seeing BG curves like this one. This is presented as an example of GOOD control. Average of 154 mg/dL and time in range 71%! My current average is 101 mg/dL and time in range is 97%.. I am not saying the person from the diagram is a bad diabetic! I am saying that apparently, such results are normal post-honeymoon. Look at these 300 BG levels...

These are examples of what I am achieving right now. The top two were very good days. The bottom is an example of when I mess up a bit.

Now, it is not like I can just roughly bolus and have results like the good days in that picture. I have to count carbs very carefully, pre-bolus properly, and can't eat too fast. I didn't do it like that at first, and regularly had peaks of 190 mg/dL or higher. I also don't do low-carb, but my carb count isn't so high, at least not compared to traditional Western diets. And I eat "safe" foods almost always ("safe" as in: I can accurately count carbs and don't have to roughly guess). The bottom graph also shows how apparently I made an error at dinner time, because the BG kept increasing constantly. I know you'll probably say that this increase is nothing (it peaked somewhere at 140 mg/dL), but I get all worked up about it, as you can probably guess from the huge number of scans.

So, is the 670g graph what I can realistically expect? Is this how it is for most T1Ds post-honeymoon? Or is it like this mostly if you eat lots of carbs and don't practice strict control? In other words, are graphs like my current ones even remotely possible post-honeymoon?
