You need at least 3 and preferably 4 public NTP servers in order for your local server to make decisions about which one is giving the most accurate and reliable time at any moment. 2 is not enough since there's no way to decide which is better. 3 allows 2 to gang up on the third. 2-24 nodes is nothing. Even bombarding the NTP server with queries will barely be noticed. Don't forget at a minimum a node won't send a query more frequently than once every 64 seconds unless you are using a badly implemented NTP client.
