This stand development is really just an excuse or an attempt to get an 'automatic developer.' Stoeckler (with two dots above the 'o'), developed a two bath method of automatic development (AD) for 35mm in the late 30s, this was for thick emulsions, then Thornton refined his formula in the 70-80s for our thinner emulsions. Later Thornton had many two bath (AD) and they were successful for roll film and in particular 35mm roll film. These methods were to extend the tonal range, BUT also to let middle tones and shadow develop to complete and normal contrast (which stand is not designed for). I have my own variation for these methods not that it is anything new I got it from someone on APUG. But it does almost do AD, you can get stops from 12 to 6 with reasonable contrast. Flat shots I bump my EI up to add contrast, but still I have to Photoshop the contrast a little. The wonders of these past pros makes it possible for us hobbyists to use TriX in almost any developer and get great shots. Now, TmaX films are a little harder.
