I promised to try to get some information about Garmin pace functionality...
I ask myself how Garmin is solving this problem or haven´t them solved the problem? Does anybody know if the Forerunner 205 / 305 or the 310XT show the actual pace while running in true values without jumping more than 10sec/min when running with a constant speed?I also had this question in my mind and I will try to ask somebody...
In the meantime I have asked about 3 persons about this subject (all using a 305 model). The conclusion is:
Also the Garmin 305 is far away from showing a perfect pace value !
Garmin offers a smoothing function for pace with 3 different user configurable modes: Slightly, medium and maximum.
(Geoffrey, did you read this ?: "user configurable" !
All persons, I asked told me they are using the medium smoothing mode. (I assume, this might be the default setting,
and they didn't want to change it...).
Anyway - the result is:
* The values are not reliable. Nobody wants to bet that a displayed value of 5:00 Min/km isn't 5:20 in reality.
* The values need a long time to respond to a speed change. Maybe it's okay for a constant speed, but not usable for
shot distance interval training.
So - this again shows, that the display of current speed (or pace) is not so easy for slow movements.
However - the fact, that Garmin isn't able to create a useful pace display, doesn't mean that GlobalSat should lean back
and forget this job ! Perhaps this is a chance to outperform the Garmin technique ?!
... on the other hand... there is an old saying... I don't remember right now... I will have to catch up on that...
Anyway - Geoffrey: There were a lot of useful suggestions:
* Average for 10,20, or 30 sec.
* Average for 100m, 200m or 300m (this was your own suggestion !)
* Moving average, median algorithm or whatever...
Did you try to implement one (or more) of these suggestions ? What are the results ?
Does it work ? Why not ?
And please: Take some more time to explain !
We tried 16 points average, but response is too slow.
are not very helful !
Who's response to what is too slow for what ?
