Occasionally we could, but I don't think there's any benefit other than helping answer the mystery of the AM bounce. The way I see it, she's either dropping quickly at +6 and then shooting back up for AMPS, or she's staying high until AM. I think she's just staying high otherwise we'd see better AMPS numbers like we are with PMPS. When we start seeing smaller increases or even drops at +3 I think for safety's sake it would make sense to get more overnight tests. But right now with the numbers we're getting and the data we have from the morning, I don't see Luna's PM numbers moving up and down that much.
That being said, I should have checked again on 7/15, 16, 22, & 24. She barely climbed at +3 and knowing her low is usually around +7 or +8, she could have dropped to green those nights.
