Since you’re going thru all the trouble to detect duplicate rides (definitely a useful feature!), I was thinking it might be cool to Merge the data sets, at least in some situations where there is overlapping (in time) data. This would be really handy to help with power meter calibration, for example.
I suppose another way this could be accomplished would be if the Xert EBC app recorded ALL the data streams that are Added. I don’t think it does this right now at least…
The alternative often involves using multiple apps and/or using lots of marginal FIT file tools online (all over the place) to edit the resulting data sets in various ways, remembering to Flag duplicates in some cases (where auto detection fails if data sets don’t span the same timeframe closely enough), and often deleting or keeping the “extra” data sets separate from the data you actually want to influence your Fitness Signature.
