If google maps records it as if you were driving down the yellow line, and you make lots of left curves, then google's distance will be shorter than yours.
I used the ruler..where you lay your own path. I tried to compensate by staying on the right side of the road. I even followed the normal path of a turn where appropriate. So, the inaccuracy is probably mostly from hills and curves where I didn't mark them exactly right.
