E Major Guitar Scale
The E Major guitar scale contains the tones E, F#, G#, A, B, C#, D#, & E. Those tones correspond to the frets 0, 2, 4, 7, 9, 11, & 12 on the 1st string (& the 6th).
E Major Pull Exercise

What fingers did you use? Try doing the exercise using only 1 finger, but try all of them (1, 2, 3, 4). Which single finger works best?
After that, try combinations, such as the 1 & 3, or 2 & 4. There is no right way to finger the exercise, just better ones.
Try to get the pulled tone the same volume as the picked tones. Pay attention to the direction of your picking (down - pull - up).
You can get this moving pretty quick with smooth picking & shifting. Depending on your fingering, you will have to shift (change positions) to get to higher tones, so...as soon as you pull, start shifting. The shift is a planned part of the pull (a snap).
Derivative vs. Parallel
Numerical Chromaticism can also be used to understand this system. By calling the Root the 0, rather than 1, basic math tells us the distance between tones in the scale. In Numerical Chromaticism, the diatonic (derviative) tones of the Major scale would be 'spelled' 0 2 4 5 7 9 11. The non-diatonic (parallel) tones would be the 1, 3, 6, 8, & 10.
