Somthing you may want to consider doing, is taking out all the variables. If you're shooting consistently (time-wise and dose), you may want to feed consistently. I'm talking the specific type of food, the uniform timing, and quantity. When Hershey came to camp, Libby had cut his food into equal sized portions, and he ate at PS and +6. I'm not that consistent with Grayson, but am now recording what I'm feeding him, when, and how much on my spreadsheet (insert a line between each day). This will help me see patterns I previously had missed, and will offer some explanation to why he seems to stay so flat (when some of it is likely food induced climb). I also buy the cases of single variety FF - so right now, I'm working on Classic Chicken. Yesterday, I used the Ocean Whitefish for between-meal snacks, as they are 0 carb, so, in theory, no food spike. But you don't want to stay on 0 carb OR seafood for any length of time... I really use it more as a treat when I'm REALLY watching the numbers.
