I develop two sheets at a time in a tray.
The film is pre-soaked.
I put the two pieces back to back and agitate by turning over the pair every 30 seconds. This provides plenty of agitation because the size of the film moves the chemistry effectively as it is removed and returned to the developer. I am able to turn the film by either long edges or short edges.
I have no problems with bromide drag or over oxidation of the developer.
My most common developer is Pyrocat HD.
