I guess that’s what I meant - in the absence of any actual history, maybe 200 is the default value it uses. I found another post in the forum which suggested you can fix your FTP history, disable strava sync with “remove imported data” ticked, wait 48 hours and re-enable sync to re-import them. But having to wait 48 hours seems like a bit of a pain… maybe contact support to see if that’s the best approach. Things might have changed since then!
Here’s the post I found: Re-syncing Strava activities?
