Made him the exact same breakfast 3 days in a row, his CGM within 20 points so gave the exact same dosage, always 12-15 min before he ate.
Wednesday he was high all morning, because he was on day 3 of the insulin in his pod, and it had lost some potency
Thursday he was dead straight across all morning, everything was perfect
Today he has gone low twice already and has had 2 snacks because his class is going on a field trip and he was bouncing around with excitement
