Mayo, usually I only see a scape that ends up between to growing points resulting in two fans where there was only one. I'm not at all sure how often those extras grow.
Also, this is only one method I see with the daylilies. They put fans up beside older fans - sort of a normal type increase - and a few will have new fans put up a few inches away from the main clump. Those last ones have to have run underground out from the clump and then came up. Since mine are grown in containers, I'm not really sure how far away from the clump those might grow. Mine have come up at the edge of the container because that's as far as they could travel, but there have been as much as 8 inches between the new fan and the main clump. As the clumps grow in the containers, that kind of increase is going to be hard to spot.
