Well, that is what is so interesting--you know how he repeated himself over and over in his publications, Judy? He essentially used the same document in both magazines and books with some modifications. He talked of some giving 10 or 12 printings, he knew someone who did 25-30 coats on a gum, but he gets it all in 4-6. So he is even doing a couple coats more than a tricolor. His di of choice was sodium, but you are right in that he did use dichromate 1.65x the gum, so more dilute than the 1:1 usual.
PS and no my knee is not better--probably tore the ACL slipping on the wet darkroom floor and probably requiring scoping which is a nice term for surgery.
