With the next HRV4Training Coach update you'll be able to select a custom range of dates to use to compute your desirable range (basically your normal values, or what in literature is called SWC, smallest worthwhile change) as well as to choose how wide you want it (half a standard deviation (SD), 1 SD, etc.). This update is a bit on the technical side, but it can be useful after you've collected a few months of data and are trying to make sense of long term adaptations. When looking at the big picture day to day variations become less important, and we tend to focus on baseline (7 days moving average) changes with respect to training load. In this context, it can be useful to select a timeframe to determine the desirable range, typically the first few weeks of base training, and then keep the SWC small so that you can analyze baseline deviations, similarly to what is explained by Daniel Plews and Paul Laursen in this post. We hope you'll find this feature useful! A couple of screenshots showing how this feature works. You first need to select the Advanced view under "Physiological data": Then you can tap a measurement to select as start date on which to compute the desirable range / SWC (and similarly a stop date): Finally you can pick how wide you'd like to have your desirable range / SWC: And the app will recompute it and show the yellow bar across your data based on your input. You can pick different start/stop dates for each athlete, and the app will remember them, so you need to do it only once: Enjoy!
