You've held this dose 10 cycles, I think you are good for that increase to 1.5 units. My only hesitation is whether she's breaking a bounce. Tonight is the 6th cycle after that green. If she is breaking a bounce when you do an increase at the same time, you can get a lot of downward movement which can need more attention. So depending on your availability to monitor tomorrow AM, if she's quite a bit lower in the AM, the bounce might be broken and you may with to increase tomorrow night, unless you are around to monitor tomorrow AM.
