Do I need to learn to ride with more consistant power output? Is it something you get used to as you see the power number on the screen? Is it just a case of make sure most of your interval is within the zone and don't sweat a few peaks and troughs?
Don't display instantaneous power on your Garmin. I think I use the 3 or 5 second window.
Yes, wind, grade and even road surface changes are going to constantly bump you around. Shoot for the middle to top of your range.
If that doesn't work for you, just set the dial to 400w.
