Support for fastest segment in a session #20

Open lindig opened 4 years ago

lindig commented 4 years ago

I have not used this project and would be interested for the analysis in rowing, which also has the notion of cadence (strokes per minute). But I believe another feature would be generally useful for running and cycling:

finding the fastest segment (say 500m, 1k, 2k..) within a session or segment (see below)
segmentation of a session according to something like direction of wind, or inclination

I believe this helps to create summaries that are comparable across sessions to track development.

Finding fastest segments is something that can definitely be done, and will add to the wish list for next release.

Segmentation according to the direction of wind or inclination depends on the measurement of those and the sport I guess. I do not have test data from running, cycling and swimming, and such measurements are currently not supported.

If you can share some data and device details, I'll take a look.

Thank you. I can see the problem now: wind, stream, or inclination data is not in the GPS/device data. For my own rowing analysis, I had written code (not in R) that would segment sessions into going up/down stream but that used external knowledge. It might be difficult to find a general solution here.

Thanks, I see. Will keep the issue open and close when support for fastest segment is in trackeR.

I recently thought about this again and believe a generalisation would be interesting, too: detect the fastest n segments of a given length. Segments must not overlap. This would permit to recover spurts within a session.
