Sue:
The numbers you have been getting are essentially the same. Frankie has been surfing. There's up to 20% variance with any number. So a 97 is really somewhere in the range of 79 to 115. If you plotted this out for all of the numbers, you'd see there's considerable overlap. It tends to look like a larger difference on your SS because you're seeing both blue and green numbers.
One bit of information you don't have in your signature is whether you're following Tight Regulation or SLGS. With TR, the goal is to shoot lower numbers. However, regardless of the dosing method you're following, at some point, you need to get used to shooting progressively lower numbers. Tonight may not have been the night or if your schedule can afford for you go be off track, you could shoot at what would be +1. On the other hand, if you're sleep deprived, that's a consideration, as well.
Please keep in mind that you're likely to see high numbers tomorrow.
Just an FYI, on Frankie's SS, the last few tests aren't showing up. You need to widen the cell. You can also stack numbers in a cell if you're testing at multiple times within an hour. You have to manually color the cell, though. Gabby's SS will give you an idea of what i'm talking about.
