You are getting ahead of yourself. When you send replies to what the CO has requested, those replies go to your file, wherever it is in his/her rotating queue of 100 cases being worked at the same time. The CO will not look at them until your file has worked its way once more to the front of the queue and gets its next turn for attention. Then the CO will send out requests for all that evidence to be verified; that is, everyone who supplied evidence gets asked if that truly came from them. Only when ALL the answers are back (and that can take weeks or months) can the CO proceed to making a recommendation for an outcome, and it's at that stage the file goes for 2pc.
