After re-reading this, it sounds confusing. I should have said that 
since carbonate anions are divalent, and bicarbonate ions are univalent, 
it takes two bicarbonate ions to equal the buffering capacity of one 
carbonate anion. That means that you have to add two molecules of NaHCO3 
to equal the alkalinity of one molecule of CaCO3.

LOL. That doesn't sound any better I suppose. I quit. ;)
