(Not disputing, just trying to understand). I attributed the ZCI failure to an inability to maintain steady power, because adjusting for the gustiness caused lots of power peaks and valleys.
I'm not sure on that one. It's just the one consistent difference that would explain everything. Hop on a $12K SRM Ergometer with a 150 lb flywheel, and suddenly riding a trainer is awesome and feels like the road.
My thought is that we can adapt to the resistance/lack of inertia, and overcome it with form. Trainers are still going to suck because of lower oxygen in the room, and heat. I think you can learn to hurt people in a headwind though (it helps to be big but aero).
It's good to be able to control your power in different outdoor situations though (like ZCI's with a headwind). I can do intervals riding next to my kids at the park by alternating which brake I'm holding, and riding at 12mph. Just overcome it.
