Segment leaderboards are presently shown with anyone that as gone through the segment no mater what activity type. This is somewhat incoherent when different sports use the same segment (for example a runner and roadbiker obviously won't score the same time). This is why I'm proposing the ideal of segment leaderboards filtered by activity type. This would make segments more precise and would be an added value to leaderboards, competition wise firstly but also fun wise as it wouldn't mix apples and oranges!
Maybe this could be a user accessible filter, or maybe just automatically filtered down by the activity type chosen when recording a session?
Sorry for my english (I speak french). If you share my ideal please kudos this, Cheers!
