As i see it the twist you gave it this time just clears off the surface
of the film real well -- a tad better than usual leaving a better
surface for fresh strong developer to be there and do it's job. The
difference to me would be very very slight unless you did it every
agataion cycle.

I look at wet negs but its a problem. Tell us how those bullet proof
dots look after they dry and see how they print. Maybe they're not so bad.

Stuff can happen like you know you're going to do this new thing in the
dark so you alter your shooting; exposing approach. Then you blame the
darkroom thing.

Only one variable at a time (not that you're not doing this)

otherwise you got notin.

By the way doing continuous agatation like the Jobo you should try
thinner dilutions than 1:3 folks.

 Like 1:4 and be there. I bet it works. Works better. Work Work Work.
