addRefSchema methods return boolean indicating success/failure.
Use obj-c BOOL constants instead of C. Rename uppercase variables to camelCase.  Added a variable (schemaItem = schema[keyword]) to get more reuse out of the schema dictionary's objectForKey method.
Creating an NSNumberFormatter is one of the most expensive single-line methods in the Foundation framework (along with NSDateFormatter).  If I recall correctly, each time you create one, it allocates 100+KB of memory and takes several milliseconds to complete.  If you ever create one, make sure that you *only* create one, and then reuse it.  But preferably, just don't create one if it's not needed (as in this case).
Initializing some uninitialized variables.  Extracting the one/true false/zero checks for uniqueItems and refactoring them.  Both of these changes are in order to resolve a condition where the fudgeFactor calculation was falsified -- falseFound was already false (due to an uninitialized variable and an unreachable else-condition).  With Xcode 5.1 the unit tests are still passing now.  With an earlier version of this commit, Sam noted that the tests were failing, though I'm not sure if it's a variation due to differences in compiler versions (that would be scary).  Hopefully it was just a matter of an incomplete commit on my part.  Regardless, "it works fine for me" :-)
