If duck's are going to land where they are comfortable landing. One superior technique is learning how to call to and set-up the lead duck. Don't worry about any other duck's but that one. I Could really go on all day about how to do this. what comes to mind is a Really small timber hole I have, If the duck's are not set-up correctly they will just circle until they get bored. Thinking of another BIG hole I hunt. They really have no pattern to where they land, Except they all seem to like one side or the other day by day and no particular pattern, I just start in middle and move myself accordingly. There are some other things you can do.. IE use your terrain of geographical features IE: Thick brush, Tree's ETC as a boundary and use a close packed wad of decoys as a false boundary.
