As already mentioned upthread, more segments does not always equal more miles. You should be looking at routings rather than simply trying to force 4 segment trips. Trying to force 4 segments is often going to force an overnight layover somewhere which means added expense unless you are willing to sleep in an airport. And then there's the inconvenience factor.
