Custom Heart Rate Zones & Wonky Relative Effort

[Skaughtto]

Custom heart rate zones are a subscriber benefit but it seems like they muck with relative effort calculations. They end up super wonky compared to default scores. Have you had any experience with this? Could you test it and get back to me?

I commute so I've ridden the same route 100's of times. As soon as I input my custom heart rate zones, which are not far off from the default, my relative effort scores changed dramatically. I was using relative effort as a metric to gauge my training load week by week, but it feels like it is no longer accurate.

If someone could test the default settings and then making a slight adjustment to the zones to replicate the effect, I'd be interested to know if it's a bug in the RE calculation.

@Skaughtto if you have working to hard what easy one day can feel very hard the next day, have a look at my post, even though the sample is power data from cycling its quite relational to HR as HR relative lag and show its effect to late
