 It's used to determine if the job frequency is higher than the scheduler frequency (it raises an ArgumentError if that is the case).
 
+### brute_frequency
 
+Cron jobs also have a ```#brute_frequency``` method that looks a one year of intervals to determine the shortest delta for the cron. This method can take between 20 to 50 seconds for cron lines that go the second level. ```#frequency``` above, when encountering second level cron lines will take a shortcut to answer as quickly as possible with a usable value.
