So, is this gameplan for recovering from a bad day good?

I got a bit off track yesterday. My friend and I decided to make a cake in honor of Rue McClanahan (one of our favorite actresses who passed away three years ago yesterday- the cake was a recipe that she would make). While I planned on having one small slice, by the time the cake was actually DONE, I was hungry and I ate more than I originally intended on having.

Still, I decided to order like normal at Applebees, but I saved part of the meal to take home for lunch today. Then, I calculated how far over I went (over 800 calories). From that number, I subtracted the 300-400 or so calories I was under on Friday-Sunday (combined, not each day). That gave me around 354 calories remaining.

So, if I were to leave around 120 calories uneaten at the end of the day for the next 3 days, I should be on track with my weekly deficit goal, right? I know you aren't supposed to starve yourself after overeating, but 120 calories is barely anything, and I've been finding I have around 100 calories left most days anyway (I have over 2,000 calories most days and I'm just not able to eat them all without eating a lot of junk. I definitely don't plan on going under most days, but since I'm not on a 1,200 calorie diet, I'm not too concerned if I don't eat 100 calories here or there.)
