I've run quite a bit of Delta 100 (and HP5+) in D-76 1:3 both using manual intermittent agitation and in the Jobo.(posted 8389 days ago)First of all, given enough manual agitation for good evenness, compared to continuous agitation curve shapes are _identical_. That is, there is _no_ compensating effect resulting from intermittent agitation.
Second, if there are any edge effects that result from intermittent agitation in D-76 1:3 compared to rotary agitation, I can't see them in 11x prints from 35mm or with a 30x magnifier.
I think modern films have made obtaining significant edge/adjacency effects and compensating development pretty much unworkable, and for the most part today such things are the result of "wishful seeing," which of course I've engaged in too. We're not using Super XX any more.
