For most of the winter I've been spinning and using the 'Bike Indoor' activity on my Fenix 5x.
In Insights shows that I ride faster than 99% of other users. This is obviously false and misleading.
I do realize people use Zwift (and other training apps) and would want to track their insight. Maybe there can be a distinction in either the activity itself (to not count towards the Insight) or a separate Insight.
