time posted on the CIC website is the time it takes CIC to process 80% of the applications... so maybe 20% are completed in 6 months, then 30% in 8 months, 40% in 12 months etc - until 80% of the applications have been completed... so it is not an "average" time to complete applications.

If the application is complete, includes a lot of evidence that the relationship is genuine, and the relationship doesn't have any 'red flags', then the processing will ordinarily be much faster. In addition, if they decide based on the strength of the application that no interview is required, that saves a lot of processing time.
