I'm a data nut.
In the examples you have above, you are looking at sections that are several minutes long. So, your averages are fine. But, let's say you are looking at a 1:10 kilo effort where there is a long float for several seconds after the standing start.
When you analyze the file, you can section off intervals in several different ways:
- 0 to 125M
- 0 to 250M
- 250M to 500M
- 500M to 750M
- 750M to 1,000M
- 0 to 500M
- 500m to 1,000M
Also, let's say you are looking at yourself in a Team Pursuit. You float on the pedals A LOT when you are in a team pursuit. So, your average cadence for whatever splits you section off will be skewed lower with the zeros in there.
The purpose of buying a power meter is to get data for analysis. Period. If your data drops off, then the tool isn't serving its purpose as expected.
Analyzing the data is the
#1 reason you buy a power meter. Based on the analysis, you adjust to improve. No analysis, no opportunity to improve.
