I can't see your dashboard because I don't have an account there.
But the GPS thing. There's some debate there. The iPhone actually has a legitimate GPS unit in it, it does not just rely upone wifi and triangulation. The real magic comes in the data filtering after you submit a ride to Strava or MapMyRide. Know how it usually takes a few minutes until the numbers stop changing? that's how long it takes to run through their servers and their software and smooth out the data. Filtering programs are pretty cool, and depending on what's allowed to pass and be considered 'good' data, your numbers change in accuracy. So I'd be more interested in their filters than the GPS unit itself.
