Hi, I am using Garmin Connect a lot for 1 month or so, and I always find that there are some points where the gps makes mistakes (That's normal) and I have speeds of 90 km/h with bike... I'm not a superhero. I had 234 km/h one time.
Apps like endomondo discard this speeds because they are intelligent enough to know that if the average speed is 12 km/h, it's impossible that this point of 90 km/h is true. this is called in statistics outliers...
It would be awesome if you introduce this feature.
Thanks!
