Sorry, just one last question if it's not a problem:
C=100(R
M
−1)/(R
M
+17) How did you get this?

To answer the question with metal oxides I get the following answers:
HX 39.71% the metal is Li while X can be F, Br or I
HX 70.933% the metal is Na while X can only be F and I think there is a 70-72% HF solution commercially available see here -

HX 80.875% the metal is K while X can only be F? I'm not sure how concentrated HF solutions can go and still be stable
HX 90.363% the metal is Rb while X can only be F?
