Custom Duration Curves (eg for VAM)

Feature Requests
1

Some mountain sports the only really useful performance metric is VAM (mountaineering, backcountry skiing, maybe trail running).

I was thinking it’d be neat to be able to plot the VAM for an activity (or group of activities) on a duration curve (like power and pace).

I’ve setup a custom stream for this but I’m getting a memory exceeded error when pulling this into a Plotly chart.

  • Is it possible to create custom duration curves from custom metrics?
  • Otherwise - how about adding VAM as a duration curve type for some activities? Similar to how Power and Pace settings worj for cycling & running.

I am planning to add a new sort of chart to show a “power vs duration” type curve for any stream. That will sort this out. I am also going to add a function to the JsStats object to compute such a curve for use in scripts. This should help with memory issues with custom Plotly charts.

Awesome! Is it also easy for you to add the custom streams and stuff to the ‘compare activities’ page? So I can build duration curves for ‘seasons’ across activities.

This would be a great feature to add. Thanks
