New issue 473 by ble...@gmail.com: HR sensor being able to record R-R or at
minimum time interval possible
http://code.google.com/p/mytracks/issues/detail?id=473
After doing some test walks and exporting to CSV or tcx i see that HR
sensor data is not being recorded at minimum possible time.
Both polar and zephyr record R-R intervals, as possible a lot of you know,
you can use R-R recordings to analyze a lot of data in your training (just
see plugins in Zonefive software Sporttracks, WKO+ software, or even more
complete Firstbeat softwares), you can analyze epoc, very exact calorie
consumption, training effect, and even overtraining.
So i think that simply the app could dump these values in the exporting,
RunGPS for example dump the values to a file so you can analyze it.
The problem here is that if i record GPS with 2 or 5 seg interval and you
are running with HR to 150bpm, HOW could we integrate this HR data in the
TCX file for example? I guess we can see how real TCX data works. And mabye
some could possible send examples of real training TCX data.
i ask for this feature because i think that the app is already recording
this data and simply dumping to null a lot of REALLY USEFUL data.
I am sorry, i was a Delphi coder and a bit of C++ coder 10 years ago, but
looking Java source now makes my head spin around... maybe i could try to
install a eclipse and look if i can modify some stuff...
SORRY FOR MY BIG RANT AND MY POOR ENGLISH

Can you post info that explains the calculations? (I've found vague
references, but nothing clear-cut)

There is no need to do any calculations here, what i think is important is
to record and dump all the info the chest-bands capture, after finishing
the workout, you export this info and do all the very very complicated
calculations in the desktop programs (firstbeat, sporttracks, etc)
example:
i am running at 150bpm, so my Zephyr is sending 150 bluetooth packets per
minute, that is 2.5 per second, but i am recording 1 GPS position every 5
seconds, so obviously we are losing here a lot of information about our
workout,
what i think is necessary: able to export to TCX or SDF with all this
information.

this well.
A limitation is though that trackpoints are recorded with second resolution
and HR is stored in bytes. Extended data can be stored though. It is
possible to store sub-second resolution in GPX too.
A format like .fit may work better.
Without looking at the code, this should not be impossible.
Second resolution (or 1/2.5 s) may not be sufficient for r-r analysis
though.
