The only time it is ever 'advised' to use the entire move, is if the first hit connects while the opponent is backed up against a wall, as this is the only time all six hits will be able to connect. However, the move is highly punishable, as the 1 following f,f+3 has to be buffered, meaning that if the f,f+3 is blocked, the opponent can simply duck under the first left punch and punish with a WS launcher followed by a juggle.
