It's good to see you participating in the community @K8Heg.
Thank you for taking the time to share the inquiry about steps.
Keep in mind 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.
Before considering other options, and if you still consider the steps of your husband are not accurate, please make sure that you've tried the restart procedure as described in this article, then check if he continues to experience the same behavior. In the meantime, you can find more useful information about the accuracy of Fitbit devices and how to adjust your stride length and dominant hand settings here.
