I've heard that alot of people see a difference between the day/night cycles.
Maybe he was having a little insulin resistance, and going up to 1.2 tipped the scales for him.
If you are going to be around I think I would risk going off schedule and shooting when he gets to 200, maybe a reduced dose to tide him over till PMPS.
If he is going to bounce from the 96 he will probably do it pretty soon if you can test and catch the zoom. I'd just hate to see him get really high by the end of the day and you have to sort of start over. Just my 2 cents.
