The end result is not perfect as there are more artefacts towards the end but it fits my purpose. Here is a ‘before’ image followed by a 10-second fix and a 30-second fix. You enter the number of seconds of a period to search through and it fixes what troughs finds.
There’s a new feature in Fit File Repair Tool which Matthias kindly wrote for me (well, for the challenge really) to fix it. It’s fairly obvious where the real HRM-TRI track is but YOUR eye is drawn away from the deviations of the other lines and towards the unsightly troughs. This doesn’t cause me a great problem but when it comes to comparing HR tracks it just makes the graph look a bit unsightly. This usually works OK but sometimes periods of between 30 and 60 seconds are missed out for ‘whatever reason’. In some of my watch ‘tests’ I have either run out of forearm space or just think that one watch is enough per arm and, in those cases, my Garmin 935 goes in my back pocket and I rely on the HRM-TRI to cache one HR track as I run. Rarely I may also have a file corruption problem – either way Fit File Repair Tool is usually able to sort out my problem – a First World Problem, admittedly. Perhaps STRAVA won’t accept a certain GPX file or perhaps I want to convert a TCX file to a FIT file for some bizarre reason. Perhaps once a week, I use Fit File Repair Tool, to fix or convert a workout or fix a route file.
