Good question, but that's really a judgement call and dependent on your circumstances. If you are really hungry and/or it's time for your family to eat, then you can go ahead and compute your correction and add it in to your meal bolus. But if you have the ability to wait it might work better to take a correction and let it at least start to work before you add food to the equation. Another option is to eat a meal without carbs or with very few. Then be sure and test at 2 hours and decide whether to correct again being sure to keep track of the insulin on board. (Keep careful notes especially if your house is hectic with kids at dinner time!).
*$#@ happens, so the 202 could be a fluke, or a slow digestion of some high fat carbs. But if you see high numbers frequently at the 5 hour mark I would consider raising your basal though I know that's harder to do on long acting.
