Duke, have you measured your max-power lately and/or throughout the season? I've found that as the season progresses, my max-power drops 25-40%. It's not that big of a deal as you don't need much power to sit in a pack. But jumps, catching breaks and sprints are all affected by it. And I've found that later on in the season, to do the same efforts, I have to work at a higher-percentage of my current max-power and end up getting toasted easier.
