Well, it's like Nick said - almost "everybody" knows how to get from point A to point B on a map, but one day you take an alternate route and find that it works better for you - maybe it's a short-cut and saves time, maybe it's more scenic.
For the specific scale practice method I use
, RSoG seems to be a really good fit. Working through modal patterns, I could almost immediately "see" them in terms of the RSoG technique and I thought that was cool. No stopping to think, "minor scale, raised 6th" or whatever Dorian is. There are essentially three universal mini-patterns, and your fingers fall in place once you get 'em down (which is easy.) Little lights kept flashing.
So, in terms of learning scale patterns
, I think this is a really good supplement to the traditional patterns and something "everybody" can use, probably even beginners. So it's a short-cut in a sense, but I'm lazy and I like short-cuts.
But for learning the notes and intervals
of the scales, and linking it all together, the jury's still out ... I know there's more theory in his tutorials and videos so I won't comment further until I give it more time.
