There are multiple possible technical solutions for a range of use cases. These include:
- Download all activities as a spreadsheet, perhaps with some fingerprinting to ease re-upload replacement.
- Provide a spreadsheet-style GUI to edit activities while keeping the data within Connect cloud.
- Others that I have not thought of.
The sorts of use cases that are not currently adequately provided for include:
- Go back over all my cycling activities and find the ones with no gear (bike) associated. Select the gear for each of these.
- Find all the activities with a specific activity type and change the type.
- Find outlier values in fields like cadence>200 , heart rate > 200 (typically some sort of electrical interference) and fix the values.
- Find activities with e.g. altitude < 0 or with a variance of 500m from the adjacent points and fix it.
Perhaps you want a flag set on a record to show that it has been manually altered, but I don't care about that.
