Table top processors Re: [Leica] Chalk and Charcoal in HC110

["Roy Zartarian" <royzart@connix.com>]

The solution in the tabletop processors, as opposed to that in a 
traditional developing tank, doesn't cover the entire reel of film.  
The horizontal design of Jobo et al. would result in areas of over 
development if the rotation were intermittent.

I initially shared your concern about constant agitation until I 
attended a Jobo seminar and paid attention to the section on b&w film 
processing.  Generally a five minute pre soak in tempered water, an 
appropriate dilution of the developer, and an adjusted developing 
time with a minimum of five minutes tame the beast of 
overdevelopment.

Jobo USA has been for me a sound source of tech advice on processing. 
So you might want to get in touch with them directly as well,
