Yoyo effect in group rides - physics or settings issue?

Im using Zwift on a Wahoo Kickr Core with good Wifi but have struggled in situations like a TTT or non ERG group workouts to not overshoot when closing gaps or dropping off too much. I mainly ride on road in groups, chain gangs so am used to riding “smooth” but in Zwift, trying to keep it smooth typically results in either overshooting the rider in front, or dropping off the rear.

Is this a physics issue or are there settings that can maje this more “realistic”. Currently have Trainer difficulty set to 50% and have tried 3s power and Immediate power and cant see any difference. Help!

It’s a weird issue based on the virtual speed being calculated by power which I guess you know.

You can’t really do anything other than practise.

I’ve posted before that the way virtual gearing could work you’d expect it to fix this because you’d expect your speed to be based on the virtual gear, cadence, wheel size not power. Power would just be the result of the effort you needed to overcome the trainer resistance to spin that gear at that cadence.

If you’re in, say ‘Gear 11’ and you do a constant cadence, then, on the flat the bike should go at that speed whether people are in front of you or not, whether you hit a powerup or not, whatever happens the bike shouldn’t speed up. The only thing that should change is the resistance you feel in the pedals.

If you want to make a bike go faster (downhills notwithstanding) you have to change gear or increase cadence.

I don’t think it does work like that though. At least it never seems simple to pick a gear and spin it to stay with the robopacers.
