A friend who recently recovered from an injury just did a bit of running! And unfortunately, their personal data trackers have duplicated the data unhelpfully.
One is a smart wearable, a bracelet or watch or something, that they use to track heartrate. One is Strava (on their phone?) that helps them track distance, speed &tc.
They both reported, so now the canonical data repository thinks my friend did TWO runs.
Are there deduplication best practices for #QuantifiedSelf activity #data?
