Lather, rinse, repeat after 10 seconds of trying not to go over or under the "easy" wattage. I ended up completing one set, but getting only half a star because I had so much trouble trying to hit the wattage goals.
Halfway through the second set I gave up.
So you're using Ramp Mode, which is similar to a dumb trainer? If so, I'd recommend figuring out your cadence, in your gear of choice, at the target power. That's how I do all of my dumb-trainer power targeting. There's still some lag and some over-shoot as you ramp up, but it's easier and more intuitive to for me to feel out a cadence than it is for me to feel out a power output.
