Yes, if you have duplicate activities showing in your activity list, they will all add to the statistics including the year end totals.  You are not supposed to be uploading duplicate activities in the first place.  This not only creates the issue you are mentioning with your own stats, but can impact other users on things like local legends.  I would suggest changing the settings for one of your devices so it doesn’t automatically upload.  You can still record with both devices, but then only use the backup file if for some reason the primary device has a problem.  

Hey thanks for the response. 

I never had the intention of uploading duplicates. But one year you get a wahoo computer a couple years later you get a garment watch both of them ask you to tie to third-party services and you don't really think about services you've already tied to you just go through the process. So there was nothing intentional about it it never even occurred to me until I looked at the 24 season stats. 

Despite the fact that I travel the world and race and accumulate lots of vertical lots of hours in the saddle and on the run I'm not public so there's nothing about my stats that should interfere with other people's stats because I don't care about an fkt or being public. In fact I don't even use Strava. For me it was more of a way to back up my data. 

But I appreciate the response and it's easy enough although tedious for me to go through and delete the duplicate workouts which is what I'll be doing and then I'll change one of my devices to no longer sync with Strava even though I'm not public I don't use it and I don't really care about the platform per se as much as I care about making sure all of my data is captured and I liked the fact I could do it in one place.
