When on a Live Segment (on my Garmin 1030), the positive and negative time differences are the complete opposite of what you’d expect if you’ve ever watched a sports event on the TV.

For example on Il Giro right now - When a rider/group is behind the leader, they are listed with +minutes:seconds (Positive value)

On Live Segment it’s the complete opposite! When I’m behind I’m being shown a negative value. This goes so hard against common sense that I feel like Strava is trolling me.
