Does anybody knows how much accurate is the creation of coures?
Today I run a distance wearing 620 and 910.The 620 "shows" 12 km and the 910 12.17.
I create the same course at connect courses and it appears to be 12.6 km.
The course creator assumes that run down the middle of the road and that you not cut corners. It will be very accurate if you follow a straight line, and will be more inaccurate the more corners you take. Even so, in the worst case the numbers that you got indicate that the course creator is only off by 5% in your example.
