I noticed MGIV RC grades 00 and 0 had a terrible kink in the darker mid-tones.

You got almost no tonal differentiation on the print for quite large tonal changes on the negative - the outcome of which was to produce some very muddy flat prints.

Yes I know 00 and 0 give you muddy flat prints but the effect was to make the prints even more muddy and flat.

I noticed in the published material put out by Ilford that MGV has eliminated that particular defect, although they use some fancy weasel words to describe the change.
