So i get 3 different numbers for total ascent with the 705. The lowest is what the 705 says, second is Garmin Connect, and the third and highest is in Training Peaks.

I'm assuming Training Peaks doesn't smooth out the elevation data and thus inflates total ascent. And Garmin Connect compares the ride route with elevation data from maps?

So what is the most accurate? I'm a fan of the possibly inflated Training peaks numbers since the numbers are higher!
