Like "yeah thats pretty much it. You can set your target number; mine is currently 110, and thats what all the calculations ; corrections and meal boluses, basals; all shoot for. There is a 'hard set' low number; I think 70, that you can't change. It won't stop insulin delivery, but it will reverse correct, or remove insulin from the dose if your below that, like at meal times. If you have any questions, message me"
