There is a huge bug/feature in the Meet-up code that by attempting to keep people in the group is accelerating the whole group up hills way faster than anyone in the group is actually pushing hard enough to go. This is not something complicated like hardware calibration - THIS IS A SETTING THAT YOU SELECT IN ZWIFT!! Strava leader-boards for Zwift are completely dominated by these low power, super-speed MEET-UP efforts. It actually makes a complete mockery of Zwift’s relationship with Strava, nevermind it’s relationship with cyclists and reality!! (I know there are lots of reasons to not care about Zwift Strava segments but thought maybe since this one is actually a setting it could get fixed!)
