It would be nice when you upload your HR-information afterwards, it would be taken into account for the following:
- Average Heart Rate: 0.0 bpm
- Min Heart Rate: 0 bpm
- Max Heart Rate: 0 bpm
- and the HR-graph can be shown at "Show training report"
Shouldn't be to too difficult as the hrm-file format is pretty simple and is well documented (http://www.polar.fi/en/about_polar/business_services/device_interface_toolkit/documentation)
