The lab I worked at many moons ago processed all films in a programmable processor, so that films with the same developing time were on the same rack. That means that, for example, Ilford HP5+ might be processed together with Kodak Plus-X, (assuming they had the same dev time).

I assume this is what Swan does too. Either that or they just rely on the latitude of the film.
