3 notes per string is an efficient way to cover each position of a diatonic scale because there are typically 3 notes per position until you need to get to the next note on the next string up or down.

There are 7 patterns due to diatonic scales having 7 notes. Each note gets a chance to start a pattern. This essentially winds up being positions of various diatonic scales (i.e. modes).

That is essentially the approach I use in these tutorials to work interlocking patterns of 2 strings at a time across the fretboard.

That is essentially the approach I use in these tutorials to cover the entire fretboard.

Fair warning, though! This is advanced material that requires solid scale & fretboard knowledge & playing skills to work though. Have fun!
