Mex said this earlier, plus the post above in this thread.
I did not ignore these, but I am unclear if they answer my questions directly, or if I have to put 2 and 2 together in some way I haven't figured out yet. :)

Calcium as an additive seems to accelerate hardened lead sulfate which means no removal or desulfation
Accelerate means hardening in perhaps one-tenth the time as compared to lead antimony. This is not the exact chemistry but it will suffice as being more understandable in general
Hybrid Plates is the new norm for car type RV batteries
2% antimony positive plates and calcium additive negative plates
Uses less water than high 5% antimony true deep cycle battery
Best plate paste is colloidal lead in high percentage with a minimum of premium quality binders. This means using high purity grids
Expensive paste. Expensive binders
No substitute for thick plates
Many manufacturers BS their way with fairy tales but refuse to divulge positive plate thicknesss which demands better paste, better grids, and much more quality control
More and thinner plates is much inferior and much cheaper
That makes choosing a battery by weight alone irrational
Using computer laser robotics, Lifeline safely stuffs fewer but thicker plates and thinner but higher capacity matting into their batteries
Plate and separator alignment precise alignment are hyper-critical
Acid and electrolysis eats things for a living. A thick plate LIVES longer than a thinner plate
A critical factor of a better battery is how much abuse it can withstand yet recover
Golf car batteries, how much of a fight they offer when equalizing
