I think what they meant is...... 66 days is quite good compared to what has happened during the course of this year. People who applied in February, March, April and up to about mid May went through horrific wait times, some were close to 120 days.
Since mid-May onwards the backlog has been reduced dramatically, almost as good at any point this year (I think January applicants may have had about a 55 day wait)
CIC updates weekly on a Wednesday but usually they are loathe to update their processing times to a new month, they will hold it at the end of 1 particular month for 2 weeks (like where they are now with June) then suddenly it will jump forward eventually substantially (I would expect this weeks update to jump at least to mid July)
I think they are looking to get the processing days between 45-60 days. 45 is the best I have ever seen. 66 days is not bad in the grand scheme of things.
Good luck
