Orrrrrrrrrrrrrrr a 16X20 tray should hold a few 4X5 sheets with some space
between them? Will use a bit of solution but at those dilutions, it won't
break the bank.

DEAR TIM,
Thanks so much for doing and posting your extensive testing. I
believe stand development was good enough for the majority of Atget's photos.
Of course, he was probably using plates and his emulsions were probably more
compatible with stand development...just guessing.
Pfft. Who did Aget think he was? Some kind of important photographer? :)
*****BUT, and this is a big BUT, (as it were! LOL!!!) stand development is
supposed to be done horizontally, not vertically. The bromide drag is due to
good ol' Sir Isaac Newton's apple, gravity!!! I am not suggesting that the
very short and widely spaced agitation periods are not beneficial but you may
find they are less necessary if you lay (or even tape) the film flat,
horizontally at the bottom of a tray. You speak of tanks and holders which
leads me to believe that the film is vertical in the developer.
Yes, I have seen guidance to this effect in other places. People are using
either trays or some sort of tube that holds the film horizontally.
The problem is that I have not figured out how to solve these problems
with tray processing:
- How do I process 4-8 sheets at a time and let them stand?
- How do I avoid emulsion scratches?
I do have a sort of wild idea I want to try. I want to take the insert
from the Yankee tank (which holds film vertically as you note) and
stick it in a large tank *horizontally* thereby attempting to do a
"spaced" stand in a big open tank. If that works, I get both the
proper orientation and the convenience of multi-sheet processing. The only
issue I can see is the possibility of Mr. Newton showing up in a new with
with bromide from the top sheets spilling down into the lower sheets. Methinks
the trick would be to space the film widely.
