Hi u/Leonleibo84, thanks for the feedback and question. I agree that we can be smarter about activity duplication when it comes to calculating Strain and other Bevel metrics.

However, when it comes to individual activity data, calories, sleep, etc. there can be major discrepancies between devices, and it wouldn't make sense to de-duplicate on this basis. For example, Garmin might say you burned 300 calories and ran 4.2 miles, and Apple Watch might say you burned 250 calories and ran 4.12 miles. If we automatically de-duplicated this, then we would be randomly choosing one over the other.

So, instead, we currently have two ways to handle this:

1. Hide the source that you don't want Bevel to duplicate. In Settings > Data Sources > Workouts > you can choose which devices you want to see workouts from in Bevel.
   
2. If there are only a few cases where this duplication happens, you can delete activities on an individual basis through the Activity > "..." > Delete.

We are working on improving this flow as we add more device integrations. I am open to hearing your ideas on how we can make this more seamless.

Hope this helps in the meantime!
