@SunsetRunner A warm welcome to the Community. Thanks for the details mentioned.
Fitbit devices have a finely-tuned algorithm for step counting. The algorithm is designed to look for intensity and motion patterns that are most indicative of people walking and running. When working at a desk, cooking, or performing other activities with arm movements, a device on your wrist may add some steps. When you’re doing activities that involve arm movement—such as working or cooking—you often walk a few steps in-between stationary periods as well, so the device tries to give you credit for those steps. For most customers, the number of extra steps added by arm-based movement isn’t significant when compared to your overall stats. You can learn more about it by checking this article: How accurate are Fitbit devices?
I'll be around if you need further assistance.
