Sorry, but I missed that earlier and I can answer the question. Yes, micro and macro contrast can be normalized. I have posted the examples here derived from the work of Mike Kriss when he was at EK. Basically, you try to get higher micro contrast to improve the images from small format by adding sharpness (edge effects) and micro contrast as opposed to LF images which need much less.
Normally, a film can be designed such that in the same developer will satisfy both ends of the size spectrum, but an excess of micro contrast can leave one with halos around some tiny objects or funny looking images.
Ideally, you would need an LF and 35 version of such a film or an LF and 35mm developer pair for such a film. This latter approace appealed to Grant, and there are several approaches to solving it that I am aware of. So, you might say that I have a "solution" to the problem, and if not a full formula I have a very good starting point for designing one.

As Ron has suggested, the post by Steve does not contain a lot of truth. As far as I can gather, these are the facts:..
Bll Troop said:"I have a huge list of errata for Haist,
and if you start carefully reviewing the Theory of the Photographic Process, you will come up with some doozies."
Somewhere along the line he has taken a dislike to Ian Grant.
He will take any opportunity to malign Ians character.
I personally believe it is because he views Ian as
a threat to his preeminence as a pundit of
photographic chemistry.
I am first and foremost a silver-based photographer. I mentor
senior students from South Salem High on darkroom technique.
I keep the enlargers aligned every 3 months for Willamette
University. I teach a workshop in large format techniques
for the Photographers Formulary.
By "publish" do you mean put on online for free? Like here on APUG?I'll publish my list one of these days.
