Hi. I’m new to Xert. I have noticed that in the workout “Streets Have No Names”, ERG and ZWO files shows slight difference in FTP % intervals. Any reason for that?

ZWO

3x

  • 1m 59.4%
  • 1m 76.4%

7x

  • 4m 80%

  • 1m 100%

  • 5m 50.9%

ERG

3x

  • 1m 63%
  • 1m 82%

7x

  • 4m 85%

  • 1m 107%

  • 5m 54%

Doesn’t ERG files use actual watts whereas zwo files use a % of the ftp being set. So if you have different FTP’s in both apps that could be the issue. I’m no expert of course!

I think this is the correct answer. They might/will all show different values unless your TP/FTP is set exactly the same across all apps.
