Activity XSS significantly greater than that shown in workoouts

Training
1

Just completed an activity resulting in 157 XSS. ‘Advertised’ XSS is 111. Activity completed in ERG Mode on MyWhoosh at same wattage as that shown on Xert EBC. Often use MyWhoosh no problem and watts are watts so platform/device shouldn’t matter. Significantly the MAXIMAL EFFORT TIME is 09:11! DIFFULTY RATING 4.5 v ‘advertised’ 3. Clearly something wrong. Has anyone ever come across this before?

SMART adaptive intervals (% Reserve MPA or XSSR) will not run at intended on other platforms like Zwift or Whoosh. In this case they were harder. :slight_smile:

Note the workout preview chart shows curvilinear intervals and expected strain –

A minor change in signature will also affect XSS analysis if that BT includes a change in TP.
