Well two suspects come to mind right away. First is marginal developer. After
being used for some prints, getting closer to exhaustion would make such
problems more likely. The other is agitation during the development process.
Just like washing, rocking of the tray keeps pockets of what might best be
described as developer that is less than ideal next to the same spot on the
print. Movement in the tray should help keep the chemistry more consistent,
just as movement of the water in a wash keeps diluting the fix that remains in
the print.

11x14 tray. (Obviously, this photog is confusing thriftiness with
being a cheapskate.)
Then he puts several 11x14 prints thru. Near the end of the session,
some of the dark, uniform areas of the prints were showing wavy,
slightly higher-density lines. (These lines did not show up on
earlier prints, and they vary from print to print.)
Could this be an effect of byproducts of the development process?
