Russ, from my looking at the video you seem to be playing the third fret on the G string, the 3rd fret is on the B string.
I feel that exercise 9 is not just about moving up the neck, it also includes swapping your fingers between strings two and three, and between fingers 1 & 2 for the 3/4 frets and fingers1 & 3 for the 9/7 frets.
You're right. I don't even have to watch the video to confirm that. I can tell your right because its the most comfortable positions for my fingers to go into. I didn't even think of "reading the tab". I just did it.
Here's my attempt at actually doing the lesson :
I haven't been able to get any faster than this yet. I'm sure that will come when my fingers adjust to the positions.
