Just to let you know, with that +12 last night of 149 and the 76 two hours later, I would have tested more, last night.
We can usually tell by the +2 test whether the cycle is going to be active or not, and when the numbers are the same or the +2 is lower than the Pre Shot test, then it's often an active cycle (meaning, his blood sugars could have gone down more and more as the hours passed).
