Workouts: Watts values shown by the unit are lower than the ones set in the application

When configuring a workout in any application (in my case, intervals.icu), I set a specific watts interval (i.e, 350w). This workout is moved to HH dashboard exporting the file as .zwo and then synced with the HH unit. When it is loaded in the unit, the workout page shows 330w instead of the specific value I set in the application. Tried other apps such as training peaks with the same result. 

Why does it happen? Did I miss anything? If it is the expected behavior, in my opinion the unit should show the exact value I set in my workout application...

  Hi Edu, this is not expected. Could you please share the workout file with us? You can submit a request through here: https://support.hammerhead.io/hc/en-us/requests/new

  I have the same issue. The workout imported from my TrainingPeaks acc't should start at 130W and on the Karoo 2 the beginning wattage is only 100W.

  Got the reply from support, the issue here is that .zwo files contain the power zone in the .xml file instead of the specific power value you set in the application. Did the same test using intervals.icu and trainingpeaks with the same result. Below the .zwo output with the power values in bolt (in intervals.icu, I wrote an specific power value, not that one finally exported in the .zwo file):

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

          </SteadyState>
          <SteadyState show_avg="1" Power="0.483" Duration="180"/>
          <SteadyState show_avg="1" Power="1.161" Duration="180">
              <textevent message="2/4" duration="10"/>
          </SteadyState>
          <SteadyState show_avg="1" Power="0.483" Duration="180"/>
          <SteadyState show_avg="1" Power="1.161" Duration="180">
              <textevent message="3/4" duration="10"/>
          </SteadyState>
          <SteadyState show_avg="1" Power="0.483" Duration="180"/>
          <SteadyState show_avg="1" Power="1.161" Duration="180">
              <textevent message="4/4" duration="10"/>
          </SteadyState>
          <SteadyState show_avg="1" Power="0.483" Duration="180"/>
      </workout>
  </workout_file>

  And then, with those values, the K2 unit then matches the data with the zone configured directly in our profiles... 

  So, the workaround here is to match the power zones you have set in your application (intervals, tp...) with the zones configured in the K2 unit. 

  Tried also to export the workout in .fit format but couldn't open the file with the standard text editor, and to be honest I didn't investigate further.
