One Finger Pentatonic Scale Exercises?

I just saw a video of Paul Gilbert demonstrating position shifting tips.

He recommends practicing pentatonic scale patterns with one finger at a time:  I do, too, and have been for YEARS now.

In fact, it's sort of surreal how similar how he went on about the subject compares to what I've been saying (as some students know).   IMO it's very methodically logical, and for some players at a certain point in their ability it's exactly what they need to do.
