I had initially send 2 reconsideration requests in the month of December and got back a reply in about 11 days precisely. Then another reconsideration request was sent in February, again the reply got was within 11 days from submission. I have done 3 reconderation requests on one site, each time removing more links and each time the reply has come back exactly on the 11th day. I have also had reports/seen other people saying 10-11 days. My thinking is this gives them time to crawl the whole web again to see if the links are there or not. If you think about it if the computer knows what the threshold is, there is no reason to employ an army of people to deal with the 5000 requests they get a day.
