You can easily create custom fields like this using a little Javascript. Click “Custom” under the activity timeline chart. I added min and max SmO2 fields. This is what the script looks like for max:
{
let smo2 = streams.get("smo2").data
let max = 0
for (let i = 0; i < smo2.length; i++) {
let t = smo2[i]
if (t > max) max = t
}
max > 0 ? max : null
}
You should be able to see those on your 24th March ride. You need to do Actions → Analyse to compute them for older activities. They can also be added as columns on the activity list view. When you are happy with them fill in a description and set visibility to “Public” so other people can use them.
You can create similar custom interval fields.
