In this post: You will learn about the interval summaries that display after you complete an interval.
In version 1.3.5 we added a prompt that displays in the upper right-hand corner of the workout screen that gives you information about the interval you just completed (screenshot below).
What does each line of display mean?
Interval Time: The top line indicates how long the interval you just finished was. Depending on the workout, this can be a nice reminder of just how painful even short periods of time can be ;)
Average Power: The second line displays your average power for the interval. Nothing too complicated here.
Distance from target power: The third line indicates how close you came to your target power. So, the screenshot below indicates that the rider was two watts below their target power of 403 watts.
Precision: The fourth line (related to distance from target power) displays how accurate your power was throughout the interval. Precision is defined as the percent of time that power was +/- 10 watts from the target.
The idea is to promote staying close to a target during the entire interval.
I used this on Beacon yesterday. I think the precision of the intervals were 50%, 55%, 57%, 65%, 55%, 40%. So even though I was always pretty close to the target with average power, how smoothly I delivered the power changed quite a bit from one interval to the next.
You can see that concentrating on it produced a much smoother graph than a few weeks before when I did Carson.
I hope this will be useful data to look at during a ride. We'll eventually add it to the ride summary as well.
+/- 10 watts is just a starting place. With my power tap, I would have liked +/-15W better but I think for virtual power and Computrainer. +/- 10W might be to big of a range. Let me know what you think after you try it.
Cadence: The fifth line will display your average cadence for the interval.
Note that if you have a heart rate monitor paired, this will also be displayed in the summary.
