Anyone else here using a Ketonix to measure breath Acetone (BrAce)

I bought one a couple of months ago and I'm mostly happy with it. Although it's initial cost is high you can use it as often as you want by just blowing into it so it's longer term cost is lower than blood testing. One good thing is you can try out different foods and see if they have an effect.
I'm finding that while I'm eating (keto IF 16:8) I'm normally in the blue range which is defined as "basal ketosis" - between 1-4ppm BrAce. If I fast (or just skip lunch or do some fasted cardio), it leaps into the 10-20ppm range. But, when I return to eating (keto around 20-30g carbs), it drops back down into the 1-4ppm blue range again after a few days. Was wondering if anyone else is managing to keep it in the green range without fasting / fasted cardio? I'm eating around 150-160g of protein every day but I'm lifting heavy weights 5 days a week.
My target numbers are:-
Calories 1676
Protein 165g (39pc)
Net Carbs 20g (5%)
Fat 104g (56%)
There's a study I read that says that 2ppm BrAce is associated with around 250g of fat burning per week. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737348/ - I'm not sure if there's a linear relationship or not (eg 8ppm = 1kg of fat per week).
I know that 'chasing ketosis numbers' is not necessary or maybe not even helpful but I find it motivating to get the confirmation I guess..

I would personally just go with any ketone level as a positive and not particularly care how high it actually is.
I’m not treating a neurological disease so high Ketones aren’t a goal for me.1 -
@Barry7879
I was using the Ketonix for awhile since I was using the ketogenic diet for treatment of seizures and wanted to make sure I was maintaining a consistent level. However, I found that I could have different readings within minutes and wasn't sure it was actually accurate.
Have you had that problem?2 -
Mine has been sitting in a drawer for years. It did what it said it would do, I just stopped worrying about the answer to the question.1
