Pacing insight (as a field) and chart with calculated value

[david]

For the first one you could probably create a computed activity field with a script to do that. This would also work as a custom interval field. You can get the velocity_smooth stream and work with that:

{
  let velocity = streams.get("velocity_smooth").data
  
  function avgVelocity(start, end) {
    let tot = 0
    let c = 0
    for (let i = start; i < end; i++) {
      let v = velocity[i]
      if (v) {
        tot += v
        ++c
      }
    }
    return c ? tot / c : null
  }
  
  let mid = Math.floor((interval.start_index + interval.end_index) / 2)
  let first = avgVelocity(interval.start_index, mid)
  let second = avgVelocity(mid, interval.end_index)
  second ? first/second : null
}

Custom interval fields

Intervals.icu now supports custom fields for intervals. You can enter the values manually (e.g. from a test of some kind) or compute them using JavaScript code. Click “Fields” on the activity timeline page and then “Add Field” to create a new field or search for an existing field: [Screen Shot 2022-12-26 at 15.44.04] Note that the fields are specific to the athlete being edited. So if you are coaching people, create fields for yourself and then use the search button to add copies to your athl…

Would it be possible to create a chart with a custom/calculated value/data stream

Not yet but that is high up on the todo list. Also creating such streams from messages in the fit file.
