I have often left either higher LC or MC food during cycles where the preshot was lower than I'd like. I think that's a good idea, since you are still new to lower numbers, and are starting to get a feel for how carb sensitive he is and how the insulin is working for him. Of course, if he decides to give you a bit of a bounce, then you won't need to worry
ETA: If he decides to give you a number you aren't comfortable with, you can stall for 20 Minutes, don't feed and see if the number is rising on its own and post for help, If the number still doesn't seem in your comfort range, you can also skip. The depot may still have an affect, so you'll still want to have food available for him.
