Martin (1992: 362-3):
In [5:36] for example the actions of the yachts during the race are divided into three main strings: manœuvering, covering and leading. Proto-typically, the manœuvering actions are extended by a Medium and enhanced by a Circumstance of direction, the covering actions are extended by an Agent and a Medium, and the leading actions are extended by a Medium and enhanced by a Circumstance of measure. These configurations are outlined below.

[1] In SFL theory, the relation between Process and Medium is complementarity, not extension. A Medium does not extend a Process because one cannot be construed without the other. Every Process unfolds through a Medium.
[2] Because Agent is defined as the participant that is the external cause of a Process unfolding through a Medium, the expansion relation with the Nucleus is enhancement, not extension.
[3] In SFL theory, this is termed a circumstance of Extent: distance.
