HI. I had the same questions too. My file was transferred on 7th Feb to LVO pretoria. I found the following in last year forum. R10: Completeness Check

A11.2: Eligibility Check (Minimum Eligibility Criteria 67/100; CRS Score Check and Selection Criteria)
http://www.cic.gc.ca/english/resources/tools/perm/express/refuse.asp
If Application is with Local Visa Office, then in 95-99% cases, it has got passed R10 and A11.2 Reviews with the positive recommendation, however, there could be exceptions to this.
If the applicant’s total score is equal to or greater than the pass mark set by the Minister, and the applicant passes the A11.2 assessment (if the applicant applied under Express Entry on or after January 1, 2015), the Centralized Intake Office (CIO) will forward the entire application, including the result of their initial assessment against the selection criteria, to the office identified by the applicant for processing for a final decision.
If the applicant’s total score is less than the pass mark set by the Minister and/or the applicant does not pass the A11.2 assessment (if the applicant applied under Express Entry on or after January 1, 2015), the CIO will make a negative selection decision, record the outcome and reasons in GCMS, and send a letter to inform the applicant that their application has been refused.
