Is there a way i can see average power and normalised power only for a selected on-off block of intervals (for example only for a block of 10 x 30s on and 10 x 30 off)?
So each 30s on is one interval? If so there is an outstanding feature request to display “interval” stats and so on for the currently visible part of the activity.
If you have one interval covering all the 30s ones then you can just click “Fields” and add NP etc.
