You are still following SLGS? Just want to be sure.
I think one reason you got the number you did today was waiting to test him when he was coming down really fast (no judgement; just an observation). His +2 was significantly lower than his AMPS so it was a good signal that he was going to be very active today. I would have fed that +3 with a MC food and retested him in one hour max to try and prevent the drop below 90.
If he were on TR, I’d suggest you start holding doses for three drops between 40 and 50 but he’s not. If he were mine, and since you have calipers, I’d just reduce to f4.25u. I don’t have a lot of faith that he will hold this reduction (perhaps by me saying that, he will

).
I’m seeing failed reductions for the reason I stated above. I think he’s giving you some pretty good clues about when he’s going to drop and when you need to manage the curve with some food. Let us know if you need or would like more info on that.
I’m still going to hope he does well with the reduction!!
