I agree with pancreaswanted. If you return to target properly at 3-4 hours after a meal, then the total bolus was right on target. A spike (or even a low) indicates a mismatch in the timing and/or profile of the bolus. Depending on the meal, you may want to inject 15 minutes or more before the meal (fast acting carbs) or even after them meal (low carb, mostly protein fat).
But most important of all, I would tell you to not sweat the small stuff. None of us are perfect, we are just human. Just being able to count your carbs and bolus the right amount is a good standard. Many people might even tell you to not test at 1 hour.
ps. If you are eating "only" bread or "only" applesauce, that is not low carb, it is a small portion, but not low carb. A cup of cottage cheese with a few blueberries, that is low carb.
