Thanks James,

But if Ca+2 and Mg+2 are the most common, why don't their values add up to most of the other two values? (12+15 versus 93 and 66) Sorry if that's a dumb question, just trying to grok the relationships here. And, "given those readings" where do these values fit in along the spectrum of possiblities? Are they high or just average?

Thanks,

TW
