I managed to get hold of a Paterson orbital and motor drive for sheet film processing. As it's continuous agitation do I reduce the development time as per the Jobo type processing? In the handbook Paterson recommend a water bath to temper the unit. Will the water bath negate the reduction in processing time?

I have used the manufacturers recommended times for continuous agitation / machine processing. I use the times for my ambient temperature, so I've never had to bother with a tempering bath, but one could double up as a pre-soak.
