When you do a hilly or windy course, you'd have to adjust your watts per 20 minutes somewhat to take that into account.Sorry, this is misinformation. A hill or a headwind does not affect your power output. On the other hand, heat, fatigue, injury, or illness might.
I'm thinking that he meant on a hill or headwind you'll be going a little harder than you should (or your target) and on the next 20 min lap you should adjust your power output to bring the average power back down.
