After several hundred miles with Zwift riding a Computrainer vs Stages PM (with a mag trainer) in the game (sometimes back to back), I have observed that the ride is significantly more difficult with the Computrainer. With good calibration, it is easier to maintain a given power and draft another rider using Stages and a dumb trainer. It was also easier to go downhill much faster with Stages plus the dumb trainer. Now I see how riders can go much faster than me down the hill while using less wpkg when I am on the CT.
Drafting is still unrealistic with computrainer. I have to maintain nearly as much wpkg or sometimes more to stay with the lead rider.
Perhaps one issue is that a dumb trainer can not simulate realistic momentum compared to an electronic trainer. Probably no way to correct this.
I could see that if someone is using a dumb trainer with just cadence/speed sensor, the ride would be highly unrealistic.
We should have a way to see next to a rider’s name what class of equipment is being used- ET (electronic trainer), PM (power meter), Sn (sensors), etc. That way , I know why I cant even suck their wheels going downhill.
