Bob, thanks for that info. Much much appreciated. I was just wondering, an ongoing curiosity of always tweaking stuff on my end.

You're saying, "Agitation can have a tremendous effect in the highlight region which would cause softening in the highlights, otherwise I do not have an answer" - along maybe w/ just using slightly different dilutions, is where I'm seeing the difference.

Might shoot yo a PM quick as not to take this further off track.
