Sorry I wasn’t on earlier.
A couple things for the next time you see a low number at preshot and are able to monitor. First, if you stall try stalling just 20-30 minutes before testing again, you want to get insulin in before he starts shooting up, as there is still a couple hours after the shot before onset for the numbers to rise. Second, if he’s flat or rising after that stall, SHOOOT! He shouldn’t be going down after that unless you stall too much. Lack of food from the delay can lower the BG’s. Third, a stall acts like a reduction. Tonight you both stalled and reduced the dose. You don’t need to do both. Lesson learned and an opportunity to gather data. And lastly, I am not a huge fan of the reduced dose as a safety measure anyway, as the depot will usually make the first part of the cycle play out like you had shot the full dose anyway, but with the reduced dose you just end up with higher numbers to start the next cycle.
I really liked blue preshots. Shooting lower means much flatter cycles and more predictable cycles. Cycles starting pink or worse can go anywhere.
One thing to remember with an acrocat, there is no one good dose, only the dose that is good at the moment. Don’t get attached to any given dose. Have you thought about what dosing methodology you want to use?
