As noted by Loris, I did find that a 15 minute delay after exposing and
before developing a cyanotype increased shadow separation nicely, though
I'm not sure if that would explain Joe's finding, even if I could follow
it, which I could possibly when the republicans leave town & the dust
settles, but not necessarily.

HOWEVER, I think Mark is onto something that may apply -- think
intermittency effect !
