Systems and methods for ensuring sufficient bolus dosing for meal compensation

A method of compensating for meal ingestion in a drug delivery system comprising:

• automatically detecting a meal event using at least a first classifier model configured to evaluate a first sliding window of analyte values corresponding to a first duration based on a current timepoint and a second classifier model configured to evaluate a second sliding window of analyte values corresponding to a second duration based on the current timepoint that is greater than the first duration, wherein the first and second classifier models are each applied at successive analyte detector output intervals as new analyte values are received;
• calculating a safe bolus dose to be delivered to a user based on the detection of the meal event;
• delivering the safe bolus dose;
• monitoring blood glucose levels of the user;
• and
• compensating for further excursions in the blood glucose levels of the user in accordance with a medication delivery algorithm of the drug delivery system.
