When looking at the ‘Activities’ information provided in the Companion app on my phone after a ride, there are figures for those I follow (in orange) and, presumably, everyone on the ride (in black). Do these numbers represent everyone who registered for the ride, or everyone who actually participated?
I’ve noticed that when I log in to zwift.com (which I do only about twice a month), the ‘Activity Feed’ information for the same ride shows fewer people in each of ‘Zwifters you follow’ and ‘Total Zwifters’:
These are from a group ride yesterday. I didn’t think that there were so many people present during the ride – would have estimated 140 maximum, but maybe that’s due to Zwift only showing the x closest avatars to you in the mini map and in game.
