When you run on a track, and use the lap button on your watch to mark each lap (or multiple laps), the data in PowerCenter or other analysis platforms may show that laps were recorded too short.
This is caused by a delay between the actual recording of your pace and distance versus what is reported on the watch. The watch can lag about 5 seconds, which can be many meters if you are running fast. For example, if you run a 400-meter interval at 3:30 min/km (6:40 min/mile), you travel as much as 24 meters in 5 seconds.
These are a few possible workarounds:
1. Come to a complete stop after the interval and wait 5 seconds on the line for the watch to catch up (you can wait for pace and/or power to drop to zero)
2. Wait 5 seconds before marking the lap complete.
3. Do not mark laps on your watch, PowerCenter will still correctly analyze your run.
