I'd like some input here from you GPS device users: some of these things are plotting points every 3 feet or so. That's a lot of data for this purpose and slows things down more than it's worth. I'm probably going to throttle it by adding some "if this point is less than n meters from the previous one, ignore it" logic when uploading. My question to you is "how many meters should n be?".
I know with the Forerunner 305, there are two recording options:
record every second
smart recording - records a point when you break from a straight line
I believe the older Forerunners used smart recording with no other options and am not sure what other models use. My guess is that the ones presenting problems are the tracks with every second recording.
Since the smart recording records a point when you turn, I really don't want BT to erase any trackpoints. I'd suggest looking at the time between points and only sabatage those who use every second recording
It didn't take long after the 205/305's were out before Motionbased only offered limited support for the every second recording. Here is a snippet from them. Read the full thread for more details
Turn your device back to Smart Recording. MB will not be accepting activities over 1 hour that track using 1 second resolution. This restriction will be starting as early as this week so please make the adjustments soon. Using 1 second resolution is overkill and goes beyond the accuracy of the location sensing technology, cadence and heart rate interpretation unless you are moving fast. |
