Banjo Fretboard Practice

Janet Davis, author of the Janet Davis Ultimate Banjo Songbook, says that if  you practice the major chords up and down the fretboard .... taking a chord a month, following the Circle of Fifths, and pick out the root notes.......at the end of a year, you will have memorized all of the note positions on the entire fretboard.

A month a chord seems like a long time... why couldn't you shorten it to a week a chord???  And practice the chromatic and pentatonic scales for these keys at the same time?   That would see the whole thing done in three months.

This week is C Major week and next week is G Major week.
