From the R and A website:
Etiquette, Courtesy, pace of play
This section in "The Rules of Golf" states:
Players should play at a good pace. The Committee may establish pace of play guidelines that all players should follow.
It is a group’s responsibility to keep up with the group in front. If it loses a clear hole and it is delaying the group behind, it should invite the group behind to play through, irrespective of the number of players in that group. Where a group has not lost a clear hole, but it is apparent that the group behind can play faster, it should invite the faster moving group to play through...
Thanks, so under Etiquette - Keeping pace it has the section you quote but under Pace of Play it omits this information (notwithstanding how is a group (B) to know that a following group (C) can play faster if group B is not able to play at its pace due to being held up by group A in front)
