What should (or could) be done with the following? The link is dead, the context is gone (no wayback machine), and overall it is probably not that helpful. Any ideas?
The simplified formula for calcium-deficient carbonated hydroxyapatite is:$$\ce{Ca_{$10-x$}Na_{$x$}(PO4)_{$6-y$}(CO3)_{$z$}(OH)_{$2-u$}F_{$u$}}$$
The perfect formula is:$$\ce{Ca10(PO4)6(OH)2}$$
So why does the $10-x$ on the simplified formula show that it is calcium deficient?

@Martin-マーチン I think the concept is helpful, Karsten posted a new link to a different article. That said, TBH for the amount of work it would take to rehab this question, I would rather post a better one myself and mark this one as duplicate.
