	The rotational transform (or field line pitch) ''ι/2π'' is defined as the ~~mean number of toroidal transits (''n'') divided by the mean~~ number of poloidal transits ~~(''m'')~~ of a field line on a toroidal flux surface.		The rotational transform (or field line pitch) ''ι/2π'' is defined as the number of poloidal transits per single toroidal transit of a field line on a toroidal flux surface.
	The definition can be relaxed somewhat to include field lines moving in a spatial volume between two nested toroidal surfaces (e.g., a stochastic field region).
