I just went through a process to determine just that. My goal was to find development times for the Jobo that would provide curve matches for what I had with intermittent inversion agitation. The developer used with D-76H 1:1 and 1:3. I used a one-minute prerinse to avoid airbells. The results show that there is _no_ standard compensation factor that can be applied. To be specific, HP5+ in both D-76H 1:1 and 1:3 required a 25% reduction in development time, Delta 100 in both D-76H 1:1 and 1:3 required a 35% reduction, and Delta 3200 in DD-X 1:4 required only a 15% reduction.
