From an industry point of view, it would be wasting time unless it was for a paper in Journal of Food science and even there since the goal is for the audience to believe a foot note pointing out that grape and country wine follow the rule would pass.
What I find kind of odd tho is that it is accepted to use technically incorrect terminology- even by professionals.

the key is TA is a tool which is useful in producing acceptable product

Aye!

(These things need to be understood. But someday, it's gets a little deep for my ol brain. Kinda like taking a shower with a fire hose. You need to know and understand but...it make my head hurt sometimes.) :slp

Totally out of my depth here but don't different countries use different acids as their basis for TA, (grams of WHICH acid/L of wine?) so here , in the USA, TA is based on tartaric acid but France uses sulfuric acid as the measure and I think that in cider making the grams of acid are based on malic acids. And that meant that to modify TA you need to add so many g of acids AS IF you were adding tartaric or malic (depending on what acid you were basing the g/L on) to the wine and those amounts would be different. Or do I have this all wrong?

YES . . . . . . . and it is easy calculate to other systems if needed for compatibility

No, that sounds right. Review Stick's posts #11, 14, and 17 in this thread where he confirms your understanding and even gives the conversions.
