CTL and ATL are components of rolling TSS/day (2x your set constant), so any differences in CTL are likely happening in TSS. What should your check to find out?
- Check #1 is the FTP setting for each athlete. You'll need to manually set the FTP history for each athlete and ensure you have them generally matched with settings in TrainingPeaks. This can be reviewed/completed on the Athlete Details tab.
- If the FTP has been set correctly, the next step is to check the daily IF in WKO4 against TrainingPeaks. In each PMC pack, there is a daily TSS and IF chart so you can compare against the workouts in TP. They should match reasonably closely; WKO4 calculates Normalized Power in a slightly cleaner way, so it might be 1-2% off, but it should be close. If you find a time range where these are more than slightly off, check the FTP setting again.
- Check Sport Type. Make sure you have all sport types selected in the top right selection tool, as these will cause your CTL and ATL to reflect only files of the selected sport types.
