Somewhere, I ran across a formula for divided FX-2
Bath A - Metol 2.5g, Glycin 7.5g, Sodium Sulfite 35g. water to 1L,
Bath B - Kodalk 100g, water to 1L

The person who proposed it had never actually used it. I would suppose that with that much sulfite, this would be a developer that partially develops in bath A, as does D23D and Barry Thornton's two-bath.

Has anyone used this developer or have any comments?
Yes, of course, I'm going to give it a try and will report back.
