I was just giving your numbers as example. the map shows the plane crossing at 8:17, however, the video has it crossing at around 8:18 if not mistaken. I'm currently running all 3 legs now, instead of the 3 separate legs I've been doing while learning the path.
In the past I was flying from Seattle to Toledo, this would be the first leg. then from Toledo to crossing the Lewis river would be the second leg, and finally, to the Columbia as the third.
