Big word, efficacy.  People who tend to use it haven't a clue how to use it.  FWIW efficacy is used to describe the results of clinical trials.  You should have used 'efficiency' which is used to describe results in the wild.

   I can assure you that with a 99.7 percentile verbal aptitude I know very well the usage and efficacy of the word. ????
