David, I checked with a contact at USGBC about this, who got the following info from GBCI:
“CIR turnaround time is 3-4 weeks (from the time the customer submits to the time we return it to the customer). I would say this is being achieved on at least 95% of the CIRs. The ones that are not within those timelines are those that require further discussion.”
Does this sound about right in terms of your experience?
