nchubb, there is always a delay between your actions and CR posting. The creditor only posts once a month to the CRA, usually not until their billling cycle closes. Once reported to the CRA, they must then update their files.
Expect at least a one month delay in any posting to your CR. If you have any really important actions that you want posted to your CR, do them at least a month, and preferrably two, before you need to see a revised score against your CR.
