Yeah, I am familiar w/that one, mine's a little different then that, the triads are more of a visual thing w/mine to identify where the chord tones exist inside of the scale fingerings. The improvisational theory behind it was based off what Charlie Parker did, using all 12 tones to create with. What I do is place a note within one of 3 catagories: A tones (chord tones R 3 5) B tones (diatonic scale tones other then the R 3 5) C tones (non diatonic tones, which I reffer to as approach tones)
