Yes, it seems like she needs another increase. I usually do not have time to test again before going out the door and at that point, she is only +1.5 hours.
Also, we are going away Sat-Tues morning and a pet sitter will be taking care of her, so I don't want to increase during that time. Soon as I get back Tuesday morning though, I can becuase I took off the remainder of the week, so then I can get those +2s and checks throughout the day.
