This is a rather a request for a feature change:
During sprints or other timed sections Zwift compares and shows you the names and times of other Zwifters.
This is however based on your current time and not on your ETA.
So while riding the section you get „passed down“ the leader as you get closer to the finish line.
I don’t find this very motivating. Showing the record of the position based on your current ETA would motivate much more to put in an extra effort.
Probably a really small change with a big effect…
