Thought I’d add a bit - I’ve got a few more workouts done.
In zwift, it does better when you are on the tri-bike. It removes the layer of figuring out resistance change when drafting. It does better on flat terrain with small changes in elevation. I tried it in Titan’s Grove and it did ok, some of it is me just not being used to needing to shift, some of it was the trainer being a bit choppy with its responsiveness. I’m going to put on a narrower range cassette to see if that helps me.
I did Acho today in TR and it went pretty well. Other than one blip when it got too easy for about 2 seconds in the middle of an interval, there were no issues. I should mention that I also have a 4iiii podium powermeter on my left crank and that I’m using the powermatch option. Also, I’m connecting via ant+.
