This is excellent advice! It will drastically reduce the time it takes to internalize the scale, and it works for about EVERYTHING... When your EAR and your fingers teaches the scale rather than your eyes and a book it is easier to translate that skill into improvising too.Try putting the books away once you know the formula for each scale and work them around the circle by ear. Internalize and develop your ear to finger speed ratio and try to get away from academics and thinking too much. Next work patterns based off the memorized scales around the circle by ear.
the Haerle book "Scales for Jazz Improvisation" presents several mental ways to figure out the scale formula.. by steps, and also by what major or minor scale it is built from/ So it is easy to learn the "formula", then put the book away and play the scale with your ear.
