OK. The main effects on his BG are going to be these:-
He just completed his 6th cycle after his last skipped shot. That means his depot is now back to where it needs to be, so you would expect to see slightly lower numbers.
Throwing up, if he's been feeling sick beforehand (which is likely) will often lower BG.
5/9, he got 3 carb and 2 carb in the morning and a mixture of 1 carb and 2 carb between his AM and PM shots. At PMPS, you gave him 7% carb...and he had a completely normal cycle with a nice nadir. Off a 7% food. Similar situation on 5/12 - you started his day with 2% and 3% and he ran in the 300s. In the evening, he got 4% followed by a little 3% and a fair amount of 6%...and again ran a very normal cycle with some nice numbers...off higher carb (though still low carb) food. On the vast majority of days, there's such a mixture of foods between 1% and 4%, all in tiny little quantities each and often 2 different percentages in the same meal, that the average carbs from day to day are actually almost identical...if we're going to assume that the percentages are that accurate (they're not, but I'll play along for the sake of argument). And yet his numbers, day to day, on almost identical average carbs, vary quite significantly. Which lends more to the theory that he's still doing some bouncing although it's more difficult to spot now because his bounce numbers are close to what were his 'regular' numbers just a week or two ago. And that skipped shots have an effect for more than one cycle, which we already know is true with a depot insulin. Plus you're seeing regular day to day variation. I have looked at the food you've got listed, but a lot of it makes little sense on a logical level. When you give 0.5 oz of 0% and 0.5 oz of 6%, you've got yourself a 3% food. Exactly the same as the 3% food you may have given at another meal but are saying you see a difference. And then things like giving 2 oz of 4% and 1 oz of 3% - which averages to 3.66% for that meal. Which rounds right back to 4% since all the carb percentages we have are rounded. So you might as well just give the 4% because effectively that's exactly what you did give. This is why it's impossible for us to confirm that the food is the difference. If you were to feed him a 0% food for 3 or 4 days...days where you don't skip a shot and he isn't bouncing...and then 7% for 3 or 4 days under the same circumstances and you were able to see that he ran higher on the 7% all day every day, then we would agree with you. But when you're trying to control the carbs down to less than a 1% difference and saying it matters, then there's really nothing for us to see because we know the percentages you're working from aren't accurate enough to do that.
