How to Use Weight and sFTP in Charts in WKO5

If you have upgraded to WKO5 from WKO4 and find that some charts using weight and sFTP (set functional threshold power) are not displaying results properly, you may need to update the expressions as explained here.

sFTP

WKO5 assigns a different sFTP for each sport, so when building charts in WKO5, you'll need to specify which sFTP the chart should use (bikeftp, runftp, etc.). Click here for a tutorial on setting up multiple thresholds in WKO5.

Looking Up Weight and sFTP

WKO5 handles weight and sFTP history slightly differently from WKO4, and WKO5 needs to know which weight and sFTP record to use for each expression. You can do this using the lookup() function.

The lookup() function does exactly what it sounds like: it looks up the most recent weight or sFTP entry in Athlete Details for the dates designated. (Click here and click the Metrics tab for a tutorial on recording and tracking metrics in Athlete Details.) 

Here are several examples:

  • lookup(weight,now) - This expression returns the most recent weight entry as of now in the date range selected in the RHE (right-hand explorer).
  • lookup(bikeftp,now) - This expression returns the most recent bike sFTP entry as of now in the date range selected in the RHE.
  • lookup(weight,date) - This expression returns the most recent weight entry for each date in the date range selected in the RHE. 
  • lookup(runftp,date) - This expression returns the most recent run sFTP entry for each date in the date range selected in the RHE. 
  • lookup(weight,enddate) - This expression returns the last weight entry in the date range selected in the RHE.
