Probable issue in distance between Flow and SportTracks using Stride sensor

[ldegiorgi]

Hi,

i want to signal a possible bug related to the distance how it is reported in Flow and how it is reported i other tools (eg SportTracks). Today I've done a manual calibration of the Polar Stride Sensot through 3 round on a track. The watch reported 1.1km but when I exported and imported in SportTracks, it report 800m.... How it can be possible? I've the file to share with you.

Best regards

Luca

Hi @ldegiorgi,

What format are you using? ie GPX or TCX? Would you mind attaching the file(s) to this issue? (Github allows attaching files by dragging them onto the section just below the text when adding a new comment). Note, doing so will make them public. If that's not acceptable, you can email them to me at git at colby dot id dot au.

Thanks.

I use TCX. I Tryed to upload TCX files, but the system says "Unfortunately, we don't support that file type. Try again with a PNG, GIF, or JPG.".

Bummer. I wasn't aware of that limitation.

Did that session have no GPS active, or is flow.polar.com simply obfuscating the location?

I haven't received the TCX and/or training session files yet.... are you going to / did you email them?

Thanks.

Thanks @ldegiorgi, I've got the TCX file now.

The short version: You've been bitten by issue #27 :frowning:, and should upgrade :smile:

Today I've done a manual calibration of the Polar Stride Sensot through 3 round on a track.

Looking at the session in flow.polar.com, I can see you have three laps, at around 400m each (actually the website indicates that the last one was only 300m, but could just be a precision / rounding issue.

Because these are recorded by the V800 as two splits, rather than three laps, the version of Bipolar you were using (0.2.1 - as indicated by the build info at the end of the TCX file), incorrectly failed to see the part of the run that follows after the two splits - ie, the final lap.

Anyway, that was fixed in 0.2.2, so I suggest you upgrade to that or later (I'd recommend 0.2.3).

Then, if you delete (or rename) the TCX file, Bipolar will simply recreate it with the final lap intact :smile:

Let me know how it goes.
